Flowering period, April to June.
Dodecatheon Meadia.
SHOOTING STAR, or AMERICAN COWSLIP; Nat. Ord. PRIMULACEAE.
A distinct and pretty herbaceous perennial, very hardy and floriferous. Those who do not readily recognise it by any of the above names, may do so by the illustration (Fig. 34). It has long been grown in English gardens—nearly 150 years—its habitat being North America. Not only does it do well in this climate, but since its introduction several improved varieties of this species have been produced, which are both good and distinct. A brief notice of them will not be out of place here, but first the general description may as well be given.
The flowers much resemble the Cyclamen, but they are only about one-fourth the size; the calyx is five-parted; the corolla has five stout petals inserted in the tube of calyx; they are well reflexed and rather twisted; their colour is purplish-lilac, but at the base of the petals there is a rich blending of maroon and yellow. The seed organs are very long, compact, and pointed, giving the appearance of shooting stars. The flowers are arranged in fine clusters on a scape more than a foot high, each flower having a rather long, wiry, and gracefully bending pedicel; all of them spring from one centre. The leaves are radical, oblong, smooth, dented, and wavy, about 8in. long and nearly 3in. broad.
D. M. albiflorum I do not grow, but from what I remember of it, it differs from the above only in being less vigorous and in having white flowers.
D. M. elegans.—Shorter and broader in leaf, and roundly toothed; flower stems shorter, umbels more numerously flowered, bloom deeper in colour.
D. M. giganteum has a very large leaf, much larger than the typical form of the species, and of a pale green colour, and in all other respects it is larger, being also more than a week earlier in flower.
Flowering period, April to June.
Dondia Epipactis.
Syns. ASTRANTIA EPIPACTIS and HACQUETIA EPIPACTIS; Nat. Ord. UMBELLIFERAE.
This is a little gem, perhaps rather overdone with too many big names; still, this choice, hardy, herbaceous perennial is worth knowing by all its titles. Never more than 6in. high, its singular flowers are very attractive; they spring from the ground almost abruptly, are greenish-yellow and leafy in appearance—in fact, what at first sight might seem to be the petals are really but whorled bracts, which embrace the tiny umbels of flowers. Soon after the flowers the leaves begin to appear, unfolding like many of the anemones, each one springing from the root only; they also are of a peculiar colour and shape, being three-lobed and finely notched.
It will stand any amount of rough weather, always having a fresh appearance when above ground. It forms a choice specimen for pot culture in cold frames or amongst select rock plants; it should be grown in mostly vegetable mould, as peat or leaf mould, and have a moist position. Not only is it a slow-growing subject, but it is impatient of being disturbed; its propagation should therefore only be undertaken in the case of strong and healthy clumps, which are best divided before growth commences in February.
Flowering period, April and May.
Doronicum Caucasicum.
LEOPARD'S-BANE; Syn. D. ORIENTALE; Nat. Ord. COMPOSITAE.
The specific name denotes sufficiently whence this comes. It is hardy, herbaceous, and perennial, and one of those plants which deserves to be in every garden; its general appearance is that of a tender plant, from the pale but fine delicate green of its foliage, a somewhat uncommon shade for so early a season. It begins to flower in March in a warm situation in the garden, when only a few inches high, and it goes on growing and flowering until summer, when it is nearly 2ft. high. A glance at Fig. 35 will give a fair idea of its habit.
The flowers, which are bright yellow, are 21/2in. across, produced one at a time, though the leafy stems are well supplied with buds in various stages of development. The leaves, besides being so rich in colour, are of handsome forms, being variously shaped, some having long stalks, others none; all are finely toothed and heart-shaped; the radical ones come well out and form a good base, from which the flower stems rise, and they in their turn serve to display the richly veined and ample foliage which clasps them to near their tops. Although this species is not a very old plant in English gardens, it belongs to a genus, several species of which are very "old-fashioned," and, consequently, it shares the esteem in which such subjects are held at the present time.
If left alone, after being planted in fairly good soil, it will soon grow to a bold specimen. Plants three years old are 2ft. across; rockwork or ordinary borders are alike suitable for it, but if planted on the former, it should be of a bold character, so as to harmonise. I have observed that neither grubs nor slugs seem to meddle with this plant, which is certainly a rare recommendation. Its propagation may be carried out at almost any time.
Flowering period, March to July.
Echinacea Purpurea.
Syn. RUDBECKIA PURPUREA; PURPLE CONE-FLOWER; Nat. Ord. COMPOSITAE.
In the autumn season one is almost confined to Composites, but in this subject there is, at any rate, a change, as regards colour. Yellows are indispensable, but then predominate too strongly. The flower under notice is a peculiar purple with greenish-white shadings. This will doubtless sound undesirable, but when the flower is seen it can hardly fail to be appreciated. It is much admired; in fact it is stately, sombre, and richly beautiful—not only an "old-fashioned" flower, but an old inhabitant of English gardens, coming, as it did, from North America in the year 1699. In every way the plant is distinct; it does not produce many flowers, but they individually last for several weeks, and their metallic appearance is a fitting symbol of their durability. They begin to expand in the early part of September, and well-established plants will have bloom until cut off by frost.
The flowers are borne at the height of 2ft. to 3ft., and are produced singly on very thick, rigid stalks, long, nearly nude, grooved, furnished with numerous short, bristle-like hairs, and gradually thickening up to the involucrum of the flower. Said involucrum is composed of numerous small leaves, a distinguishing trait from its nearest relative genus Rudbeckia. The receptacle or main body of the flower is very bulky; the ray is fully 4in. across, the florets being short for so large a ray; they are set somewhat apart, slightly reflexed, plaited, and rolled at the edges, colour reddish-purple, paling off at the tips to a greyish-green; the disk is very large, rather flat, and furnished with spine-like scales, whence the name Echinacea, derived from echinus (a hedgehog). In smelling this flower contact should therefore be avoided; it is rather forbidding; the disk has changeable hues of red, chocolate, and green. The leaves of the root are oval, some nearly heart-shaped, unevenly toothed, having long channelled stalks; those of the stems are lance-shaped, distinctly toothed, of stouter substance, short stalked, and, like those of the root, distinctly nerved, very rough on both sides, and during September quickly changes to a dark, dull, purple colour. The habit of the plant is rather "dumpy;" being spare of foliage, thick and straight in the stems, which are drum-stick like; it is for all that a pleasing subject when in flower; I consider the blooms too stiff for cutting, more especially as they face upwards.
Unlike many species of its order, it is somewhat fickle. I have lost many plants of it; it likes neither shade nor too much moisture; latterly I have found it to do well in a sunny situation, in deep rich loam and vegetable soil mixed. If planted with other ray flowers it forms a fine contrast, and when once it has found suitable quarters the more seldom it is disturbed the better. It may be propagated by division, which may be more safely done after growth has fairly started in spring, or it may be done at the sacrifice of the flowers in late summer or early autumn, before growth or root action has ceased.
Flowering period, September to end of October.
Edraianthus Dalmaticus.
Nat. Ord. CAMPANULACEAE.
A rare and beautiful alpine species, from Dalmatia and Switzerland. At the end of July it is one of the most distinct and charming flowers in the rock garden, where it not only finds a happy home, but, by its neat and peculiar habit, proves a decorative subject of much merit. This desirable plant (see Fig. 36) is quite hardy in this climate, being herbaceous and perennial; it has, however, the reputation of being difficult to manage, but, like numerous other things, when once its requirements and enemies are found out, the former supplied and protection from the latter afforded, it proves of easy management. In some instances these conditions may, though stated in such few words, prove comprehensive; but in this case it is not so. The position and soil it most seems to enjoy may be readily afforded in any garden, as we shall shortly see; but, so far as my experience goes, the slugs are its most persistent enemies. Especially when in flower do they make long journeys to reach it; they go over sand and ashes with impunity, and often the beautiful tufts of bloom are all grazed off in one night. I had occasion to fetch in from the garden the specimen now before me, and, when brought into the gaslight, a large slug was found in the midst of the grassy foliage, and a smaller one inside one of the bell flowers. The "catch and kill 'em" process is doubtless the surest remedy, and three hours after sunset seems to be the time of their strongest muster. Not only does this plant suffer from slugs when in flower, but perhaps equally as much when in its dormant state, especially if the winter is mild; then I have noticed the somewhat prominent crowns eaten entirely off, and it is not unlikely that this plant has come to have the name of a fickle grower, from being the favourite prey of slugs.
It is not more than 4in. high under any conditions in this climate, and more often only 3in. in height. From the thrift-like tufts of foliage there radiates a set of stout round flower stalks, which are 3in. to 4in. long, and rest on the ground; the large heads of flowers are erect; the stalks are red, and furnished with short stout hairs and short foliage, the latter becoming sere long before the bloom fades. The crowded heads of "bells" are of pale purple colour, in the style of the bell-flower; they are an inch in length, the corolla being somewhat deeply divided; eight to twelve form the terminal cluster, and they have a fleshy calyx, with very long and persistent segments; the lower part can scarcely be seen for the ample and somewhat peculiar bract which closely embraces the whole cluster; said bract springs from the much thickened stalk and is composed of half leaf and half scale-like forms, arranged in two or more circles; the scales feather off with the leaf-like appendage, the latter being reflexed, but the whole is furnished with spines. The foliage of a well-grown specimen is arranged in tufts, the whole having a grass-like appearance. The leaves are 2in. to 4in. long, rough and hairy on the upper side, smooth and shining underneath, the edges having rather long hairs their whole length; the main root is long, thick, and somewhat woody.
To grow this plant well, it requires a good deep loam for its long roots, and a surfacing of grit will be of benefit, as the crowns should be clear of the damp loam. This elevation of the crowns is natural to the plant, and should be provided for. The position cannot well be too exposed, provided the deep searching roots can find plenty of moisture. On rockwork this subject may be planted with considerable effect. If put between large stones in upright positions, the plant will show its pretty form to advantage. The spoke-like flower stalks, radiating from the rich dark green tufts of foliage, are very pleasing. It may be propagated by offsets from strong and healthy plants. Care should be taken not only to have all the roots possible with each crown, but the young stock should be carefully established in pots before planting in the open. Shade and careful watering will be needful; too much of the latter will render rot inevitable. Soon as the flowering period is past is the best time to divide the roots, which should not be done too severely.
Flowering period, July and August.
Epigaea Repens.
CREEPING or GROUND LAUREL; Nat. Ord. ERICACEAE.
A hardy evergreen creeper, long since imported into this country from North America (1736), but only within the last few years has it won much favour. At the present time it is much sought after. It has the reputation of being a ticklish subject to grow. Many have had it and lost it, and those who still retain a specimen are loth to mutilate it for increase. This may to some extent account for the present demand for and difficulty experienced in obtaining it. For the last three years, hard as the seasons have been within that time, its flowers have been produced in great abundance on my specimen.
Usually it flowers in this climate in April, but when winter has continued open and genial, its blooms are produced as early as the middle of March, and they are in their full beauty in early April. They are white, delicately tinged with pink, of much substance and wax-like appearance. They are small, not unlike in form the lilac flower, but rather more open at the corolla and shorter in the tube. They are arranged in one-sided, elongated bunches, which rest on the ground, the blossoms peeping through the foliage. I must not omit to mention perhaps the most desirable property of this species—viz., the perfume of its flowers, which is strong, aromatic, and refreshing. The leaves are cordate, ovate, and entire, nearly 2in. long, slightly drawn or wrinkled, and covered with stiffish hairs. They are arranged on procumbent branches, all, like the flowers, facing upwards. To see the clusters of waxy flowers these branches must be raised, when it will be seen that the flower stalks issue from the axils of the leaves all along the branches. In a cut state the flowers are more than useful; they are, from their delicious, scent, a great treat. The plant is a suitable companion to the ledums, kalmias, gaultherias, and other genera of its own order.
Its culture, in this climate at least, has, from all accounts, proved rather difficult, so that it may be said to require special treatment; such, at any rate, has been my experience of it. Suitable soil, aspect, shelter, moisture, and position, all seem necessary for the well-doing of this plant. It deserves them all, and, let me add, they may all be easily afforded. The list of requirements may seem formidable on paper, but to put them into practice is but a trifling affair. My specimen is grown in leaf mould, a little loam mixed in with it, and fine charcoal instead of sand, but sand will answer nearly as well; the aspect is east, it is sheltered from the west by a wall, the north by rhododendrons, and the south by a tall andromeda. Moreover, its position is one that is sunken between small mounds, where moisture collects, and is never wanting; and when the specimen was first planted a large sandstone was placed over its roots to further secure them against drought; under these conditions it has thriven and flowered well, and afforded many offshoots. I attribute its well-doing mainly to the sheltered aspect and even state of moisture, but doubtless all the conditions have helped its growth. Its propagation is best carried out by earthing up about the collar, so as to induce the branches to become rooted, or they may be pegged near the extremities like carnation layers, but they will be two years, probably, before they can be safely lifted.
Flowering period, middle of March to end of April.
Eranthis Hyemalis.
Syn. HELLEBORUS HYEMALIS; WINTER ACONITE; Nat. Ord. RANUNCULACEAE.
This, though well known and a general favourite, is not seen in the broad masses which ought to characterise its culture.
It is nearly related to the Christmas roses, and, like them, flowers in winter, the bright golden blossoms suddenly appearing during sunshine close to the earth. A little later the involucrum becomes developed, and is no unimportant feature. It forms a dark green setting for the sessile flower, and is beautifully cut, like the Aconite. There are other and very interesting traits about this little flower that will engage the study of botanists.
It enjoys a moist soil, somewhat light; also a little shade. In such quarters not only do the tubers increase quickly, but the seed germinates, and if such positions are allowed it, and garden tools kept off, there will soon be a dense carpet of golden flowers to brighten the wintry aspect of the open garden. Many things in the way of deciduous flowering shrubs may be grown with them, their bareness in winter and shade during summer favouring their enjoyment and growth. Early in the summer they die down. From that time the tubers may be lifted and transplanted. Such work should be finished in early autumn, or the roots will not have time to establish themselves for the first winter's bloom.
Flowering period, December to February.
Erica Carnea.
WINTER HEATH; Nat. Ord. ERICACEAE.
A well-known, hardy, evergreen shrub, belonging to a genus comprising many hundreds of species and varieties, which, for the most part, however, are not hardy in this country, being natives of the Cape. The genus is most numerously and beautifully illustrated in Loddige's Botanical Cabinet. This might be thought to have no claim to consideration in this book, but I introduce it because of its great value in the spring garden, and because in all respects it may be cultivated like an ordinary border plant, which is saying a deal for one of the Heath family.
Erica carnea comes to us from Germany, but it has so long been grown in this country that it would appear to have become naturalised in some parts. In the latter part of March it is to be seen in its full beauty; the flowers are reddish-purple, abundantly produced on short leafy stems, and arranged in racemes, drooping; the foliage is of the well-known Heath type; the whole shrub has a procumbent habit, rarely growing more than a foot high; its fine deep green foliage, compact habit, and bright enduring flowers are its chief recommendations; the latter often last six weeks in good form and colour, so that little more needs to be said in its praise.
It can hardly be planted in a wrong position—on rockwork, in borders, or shrubberies, fully exposed, or otherwise, it proves a cheerful object, whilst as an edging shrub it is second to none, excelling box by the additional charm of its flowers. Not long since I was struck by the way in which the common vinca had interlaced itself with a few bushes of this Heath, both being in full bloom at the same time; the effect was truly fine, the red of the Heath and pale blue flowers of the periwinkle being so numerous and set on such a fine bright green carpet, of two distinct types of foliage, that to my mind they suggested a most pleasing form of spring bedding, and also one of semi-wildness, which, for quiet beauty, more laboured planting could certainly not excel. Most Ericas require peaty soil; in the case of this, however, it is not necessary. Doubtless it would do well in peat, but I have ever found it to thrive in ordinary loam or garden soil, so that I have never planted it otherwise, except where peat has been the most handy. It is also easily propagated, carrying, as it does, plenty of root as well as earth with each rooted stem; these only need to be carefully divided and transplanted in showery weather, just before the new growths commence being the best time. An annual top dressing of leaf mould is very beneficial.
Flowering period, February to April.
Erigeron Caucasicus.
CAUCASION FLEABANE; Nat. Ord. COMPOSITAE.
Herbaceous and perennial. This species is a somewhat recent introduction compared with some of the same genus which may be called old varieties, from having been introduced as early as 1633, as in the case of E. graveolens. Moreover, the genus is represented by such British species as E. acris, E. alpinus, and E. uniflorus. The variety now under notice is, as its specific name implies, a native of the Caucasus, first brought into this country about sixty years ago. It is a pleasing subject when in flower, and is certainly worth growing.
Its daisy-shaped flowers are less than an inch across, and when fully matured of a rosy purple colour; but, perhaps, the most interesting and attractive features about this plant are the various forms and colours of its flowers at their different stages of development; just before opening, the buds are like miniature birds' nests formed of white horsehairs, all arranged in the same way, i.e., round the bud, but the points are turned into the centre—these are the unexpanded florets; the next stage of development may be seen in buds, say, two days older, when a few of the florets have sprung from the nest form, and have the appearance of mauve-coloured spiders' legs laid over the bud; gradually they (being dense and numerous) expand in a similar manner, outgrowing their angularity, and at the same time deepening in colour, until at length we see the rosy-purple, daisy-shaped, and feathery flower with a yellowish centre. These pleasing flowers are borne in loose masses on stems nearly 2ft. high, and remain in bloom all the summer through.
About the middle of August a large plant was divided, and the flowers were then cut away. The young stock so propagated were in flower in the following June. I may here appropriately name an experiment I tried on this species two years ago. It was sent to me as the dwarf Aster dumosus, which it much resembles in the leaves, these being spoon-shaped from the roots, the others tongue-shaped and stem-clasping, but rougher and lighter green. I also saw it was not woody enough in the stem for the Michaelmas daisy. It was then near flowering, and the winter was just upon us, so, in order to get the flowers out, I covered it with a bell glass, slightly tilted. It flowered, and continued to flower throughout the winter with such shelter, and doubtless many of our fine late-blooming perennials, by such simple contrivances, might have their flowers protected or produced at a much later date than otherwise.
Flowering period, June to October.
Erigeron Glaucum.
Syn. CONYZA CHILENSIS; GLAUCOUS FLEABANE, or SPIKENARD; Nat. Ord. COMPOSITAE.
This very beautiful species is far from common. There are many facts in connection with it which render it of more than ordinary value and interest. It is sometimes classed as an alpine; probably that is only an inference, or it may be so considered by some, from its dwarf habit and suitable association with alpines. It is not an alpine; it comes from South America, and though that climate differs so widely from ours, the plant grows and winters to perfection in this country.
One of its main distinctions is its somewhat shrubby and evergreen character; of the whole genus, so far as it is at present comprehended, it is the only species with such traits; its foliage, too, is of leathery substance, and compares oddly with the herb-like leaves of its relatives; it is, moreover, as indicated by its specific name, of a glaucous hue; and otherwise, as may be seen in the following description, there exist well marked dissimilarities. But, what is of more importance, when viewed as a garden subject or an ornamental flower, it is one of the most useful as well as distinctly beautiful, as much from the fact that it produces its flowers in two crops, which extend over six or seven months of the year, as from their numbers and showiness.
The flowers are nearly 2in. across the ray, the florets being of a pleasing lilac-purple, and rather short, owing to the large size of the disk, which is often nearly an inch in diameter; this part of the flower is more than usually effective, as the disk florets become well developed in succession, when they have the appearance of being dusted with gold; the scales, which are set on the swollen stem, are of a substantial character; the numerous imbricate parts, which are covered with long downy hairs pointing downwards, give the body of the flower a somewhat bulky appearance. It will be observed that I have made no mention of the Conyza traits of divided ray florets and reflexed scales, simply because they do not exist in this species, and though there are other Conyza traits about the plant, notwithstanding its almost isolating distinctions from other Erigerons, it would seem to have more properly the latter name, and which is most often applied to it. The flower stems, which produce the flowers singly, seldom exceed a height of 12in.; they are stout, round, and covered with soft hairs, somewhat bent downwards. They spring from the parts having new foliage, and for a portion—about half—of their length are furnished with small leaves, which differ from those on the non-floriferous parts of the shrub, inasmuch as they have no stalks. The leaves are produced in compact tufts on the extremities of the old or woody parts of the shrub, which become procumbent in aged specimens; the leaves vary in length from 2in. to 4in. long, and are roundly spoon-shaped, also slightly and distantly toothed, but only on the upper half; they are stout, ribbed, clammy, and glaucous. The habit of the shrub is much branching, dense, and prostrate; its foliage has a pleasant, mentha-like odour, and the flowers have a honey smell.
This subject may occupy such positions as rockwork, borders of the shrubbery, or beds of "old-fashioned" flowers. Its flowers, being, as taste goes at the present time, of a desirable form, will prove very serviceable as cut bloom. A good loam suits it to perfection, and no flower will better repay a good mulching of rotten manure. Its propagation, though easy, is somewhat special, inasmuch as its woody parts are stick-like and bare of roots, until followed down to a considerable depth, therefore the better plan is either to take advantage of its prostrate habit by pegging and embedding its branches, or, as I have mostly done, take cuttings with a part of the previous season's wood to them, put them well down in deeply-dug light soil, and make them firm. If this plan is followed, it should be done during the summer, so that the cuttings will have time to root before winter sets in. The layering may be done any time, but if in spring or summer, rooted plants will be ready for the following season.
This subject begins to flower in June, and, as already hinted, it produces two crops of flowers; the first are from the parts which have been green and leafy through the winter, the second from the more numerous growths of the new season, and which are grandly in bloom in August; not only are the latter more effective as regards numbers and colour, but the fuller habit or more luxuriant condition of the shrub render the specimens more effective in late summer.
Eryngium Giganteum.
GREAT ERYNGO; Nat. Ord. UMBELLIFERAE.
This hardy species was brought from the Caucasus in 1820. The genus, though not commonly patronised as garden subjects, are, nevertheless, highly ornamental, and when well grown much admired. Specimens are of various heights, according to position and nature of the soil; under ordinary conditions they will be 2ft. to 3ft. high at the blooming period.
As will be inferred from the order to which the Eryngium belongs, the flowers are aggregate, of a changeable blue, and arranged in cone-shaped heads 11/2in. long; the heads are neatly embraced by an ample bract of prickly leaves; the main flower stem is well and evenly branched (see Fig. 37), each node being furnished with leaves which clasp the stems; they are, like those of the flower bract, deeply cut and prickly; the radical leaves are very different, long stalked, large heart-shaped and toothed, of good substance and a glossy green colour. The whole plant has a rather stiff appearance, the flower stems, together with the stem leaves, are of a pleasing hue, nearly the colour of blue note paper; this is characteristic of several of the genus, and adds greatly to their effect. Specimens look well with a grassy foreground or in borders.
Their culture is easy, provided the soil is of a light nature; a sunny position is needful, in order to have the tops well coloured. Propagate by division of strong and healthy clumps when dormant. Wireworm and grub are fond of the roots; when the plants appear sickly, these pests should be looked for.
Flowering period, August and September.
Erysimum Pumilum.
FAIRY WALLFLOWER, or DWARF TREACLE-MUSTARD; Nat. Ord. CRUCIFERAE.
One of the alpine gems of our rock gardens, not in the sense of its rarity, because it grows and increases fast. It came from Switzerland about sixty years ago, and for a long time was esteemed as a biennial, but it is more—it is perennial and evergreen; at any rate its new branches take root, and so its perennial quality is established. Let the reader imagine a shrub, 3in. high, much branched, and densely furnished with pale green foliage, which hides all its woody parts, forming itself into cushions, more or less dotted over with minute canary-yellow flowers, and he will then only have a poor idea of the beauty of this pretty alpine. It flowers in summer, autumn, and winter, and in certain positions both its habit and flowers show to most advantage at the latter season. At no other time during the year have my specimens looked so fresh and beautiful as in January. This I have proved repeatedly to be the result of position, shortly to be explained.
The flowers are produced in terminal racemes, are scarcely 1/2in. across, cruciform in the way of the Wallflower, greenish-yellow, and delicately scented. The leaves vary in shape on the various parts of the branches, some being lance-shaped and others nearly spoon-shaped; the lower ones being all but entire, and the upper ones, which are arranged in rosettes, distinctly toothed. They seldom exceed an inch in length, more often they are only half that size, but much depends on the position and soil. In summer the foliage is greyish-green; later it is almost a bright or clear green, the latter being its present colour. The habit is branching and compact, by which it adapts itself to crevices and uneven parts in a pleasing manner; and not only does it best adorn such places, but from the fact of their dryness, they are better suited to the requirements of this little shrub.
A sandy loam, such as will not bake, suits, and if mixed with a few stones all the better—this will be found ample food for it; poor soil and a dry situation grow this subject in its finest form. I may perhaps usefully give the method by which my specimen is grown, after experimenting with it in various parts of the garden, and also the substance of a few notes I made of it. In pots the fine roots soon formed a matted coat next the sides, when the foliage would turn sickly and yellow, so that, useful as the practice is of growing alpines in pots, it does not answer in this case. On rockwork, in vegetable soil, this low shrub grew taller, being less woody, and was killed by severe weather. On the flat, in borders, in rich soil, it did well for a season, then damped off, a branch or two together. On the flat, in sand alone, it does well, also on the top of a wall, such being a position especially provided for hardy sempervivums and a few cacti. A bit of the Fairy Wallflower was tried there in a thin layer of sandy loam, and for two years my finest specimen has occupied that position, flowering more or less throughout the winter. Where there are old walls or rockwork it should be introduced. A ready and effective way of planting it is to get a sod of grass 3in. thick; measure with the eye the size of the interstice in the side of a wall, partly cut through the sod on the earthy side, open it by bending, and insert the roots of a small specimen; close up, and cram the planted sod tightly into the selected opening. In one season the shrub so planted will have a snug and pretty appearance. It is self-propagating, from the fact of its lower branches rooting where they touch the soil. These may be taken any time and planted separately.
Flowering period, April to winter.
Erythronium Dens-canis.
DOG'S-TOOTH VIOLET; Nat. Ord. LILIACEAE.
A hardy bulbous perennial. There are several varieties of this species, and all are very handsome.
The variety shown at Fig. 38 is the large white-flowering kind; others have yellow, pale purple, and lilac-coloured blooms. All are produced singly on stems 4in. or 5in. long, and gracefully bending. During bright weather the divisions of the lily-like flowers become reflexed and otherwise show themselves to advantage. Their foliage forms a rich setting for the flowers, being variously coloured with red, brown, and different shades of green, all charmingly blended or marbled. The leaves are broad and oval, and open out flatly, so that their beauties can be well seen; if they are grown amongst the very dwarf sedums or mosses, they look all the better and are preserved from splashes. Two leaves, one stem, one flower, and one bulb constitute a whole plant; both flowers and foliage remain in beauty for a long time.
I have them growing in various positions and soils, and I think they most enjoy a vegetable mould, with full exposure to the sun, but they should not lack moisture; they seem to increase more rapidly in peat than in any other compost. They should not be disturbed more than necessary, and when they are, autumn is the best time to transplant.
Flowering period, March and April.
Euonymus Japonicus Radicans Variegata.
VARIEGATED ROOTING SPINDLE TREE; Nat. Ord. CELASTRACEAE.
It is probable that the genus Euonymus is more generally known than that of Celastrus, from which the order takes its name; besides, the latter is composed of unfamiliar genera, so it is more likely that the reader will not care about any reference to them; it may concern him more to know that the above somewhat long name belongs to a very dwarf hardy evergreen shrub, having a neat habit and very beautiful foliage. This variety is one of many forms which come under the name E. japonicus, none of which, however, have long been cultivated in this country, the date of the introduction of the type being 1804. The genus is remarkable for the number of its species having ornamental foliage, and not less so, perhaps, for the insignificance of their flowers. The species under notice (E. japonicus) in cultivation has proved sportive, which habit has been taken advantage of, whence the numerous forms, including the one I have selected for these remarks. Some of the Spindle Trees do not flower in this climate, and others, which do, produce no seed; these facts are in connection with the more finely leaf-marked sorts, and it may be inferred that such unfruitfulness arises from their hybrid nature or abnormal tendency, as seen in "sports."
The typical form is a tree growing 20ft. high, producing small white flowers, but of the variegated kind under notice established specimens have ever failed to show the least sign of flowering, though otherwise well developed and of good habit. The leaves are nearly oval, 1/2in. to 11/2in. long, sometimes oblong, sharply serrulated, of stout leathery substance, smooth, and much variegated in colour. The markings are mostly on and near the edges, and take the form of lines and marblings. The tints are a mixture of white, yellow, and pink, inclining to purple; these are variously disposed on a dark green ground. The arrangement of the leaves is crowded and panicled on the recent shoots, which are twice and thrice branched; from the shortness and twisted shape of the leaf stalks, the branchlets have a compressed appearance. The old stems are round, wiry, 9in. to 18in. long, prostrate, and emit roots like the ivy when they come in contact with suitable surfaces, whence the name "radicans." The habit of the shrub, from its dense and flattened foliage, fine colour, and persistent nature, together with its dwarfness and rooting faculty, all go to render it one of the finest rock shrubs for winter effect. The wetness of our climate only seems to make it all the brighter, and it is also without that undesirable habit of rooting and spreading immoderately.
It enjoys a sunny situation and enriched sandy loam. Where such conditions exist it may be planted with good effect as a permanent edging to walks or beds; as such it may be clipped once or twice a year, but I may add that it is worth the extra time required for pruning with a knife, as then the leaves are not cut in two and the outline is left less formal. By such treatment the foliage is kept thick to the base of the shrub. The summer prunings may be pricked into sandy loam in a shady part, where they will root and become useful stock for the following spring, or strong examples may be pulled to pieces of the desired size.
Festuca Glauca.
BLUE GRASS; Nat. Ord. GRAMINEAE.
This comes from the warm climate of Southern Europe, but is a perfectly hardy grass in this country; it is highly ornamental, irrespective of its flowers, and is useful in several ways. With me it is grown somewhat largely, and both professional and amateur gardeners have quickly appreciated its effectiveness, but it has been amusing to see their want of faith when told that "it stands out all winter." It belongs to a section of grasses of fine quality as fodder for cattle, all enjoying good soil of a light and rich nature. Its main features as a garden subject are its distinct blue colour and dense graceful habit; these qualities, however, are greatly dependent on the quality of soil, which must be positively rich. Its bloom is of no value ornamentally, being much like that of some of our common meadow grasses, and it will be as well to remove it in order that the grass may be all the brighter and more luxuriant. The blades, if they can be so called, are reed-like, but very fine, 6in. to 12in. long, densely produced, and gracefully bending. The glaucous quality is most pronounced, and quite justifies the common name Blue Grass. More need not be said to show that this must be effective in a garden, especially where bedding and the formation of bold lines are carried out; as single tufts, on rockwork, or in the borders, it looks well; whilst as an edging to taller grasses and bamboos it shows all to advantage. It is also often grown in pots in greenhouses, where it proves useful for drooping over the edges of the stage; but if it once obtains a place in the garden and is well grown, the amateur will see in it a suitable subject for many and varied uses.
Wherever it is planted the soil should be made sandy and fat with manure; in this the long roots are not only warmer, but they amply support a rapid growth and metallic lustre. As the roots can easily be lifted from the light soil without damage, this grass may be divided any time when increase is needful.
Flowering period, summer.
Fritillaria Armena.
Nat. Ord. LILIACEAE.
A charming little hardy bulbous perennial, which, although as yet a comparative stranger in this country, bids fair to find a place not only in our gardens, but in the list of the choicest spring favourites, such as lily of the valley, snowdrops, snowflake, and squills, being of the same or nearly allied order, as well as of corresponding stature. Its yellow flowers, too, highly commend it, as, with the exception of the yellow crocus, we have not a very dwarf spring flower of the kind, and, as may be seen by the illustration (Fig. 39), it differs widely from the crocus in every way.
This is a really charming species; its dark yellow flowers are large for so small a plant, being more than an inch across when expanded by sunshine, but its more common form is bell-shape; one, and sometimes more flowers are produced on the upright, smooth, leafy stem, which is less than 6in. high. The leaves are alternate linear, sharply pointed, smooth, and glaucous: Such dwarf flowers always show to most advantage, as well as keep cleaner, where carpeted with suitable vegetation; the dark green Herniaria glabra would be perfection for this glaucous plant.
It seems happy where growing fully exposed in ordinary garden soil, but it is not unlikely that it may require more shade, in common with other Fritillaries, for, as before hinted, it is yet in its trial stage. I am, however, pretty certain of its hardiness, but not about the best mode of culture and propagation.
Flowering period, April and May.
Funkia Albo-marginata.
Common Name, WHITE-EDGED PLANTAIN-LEAVED LILY; Nat. Ord. LILIACEAE.
A hardy herbaceous perennial from Japan, of but recent introduction, than which there are few more useful subjects to be found in our gardens. It combines with its wealth of foliage a bold spike of pleasing lilac flowers, the former, as implied by the specific name, being edged with a white line, which is broad and constant, this quality being all the more commendable from the fact that many variegations are anything but reliable. Speaking of this as a decorative plant for the garden, it may be said to be one of the best; however placed, it has a neatness and beauty which are characteristic, especially when used in lines, and has become well established; from early spring, when the fresh young leaves appear, until the autumn is well advanced, this plant upholds a fine appearance independent of its flowers; they are, however, not wanting in beauty, produced as they are on stems nearly 2ft. high, and nude with the exception of one or two very small leaves. The floral part of the stem will be 8in. or more in length; the flowers are numerous, 2in. long, trumpet-shaped, drooping, and so arranged that all fall in one direction; the colour is lilac, with stripes of purple and white; each flower is supported by a bract, which, like the foliage, is margined with white. The leaves are 6in. to 8in. long, oval-lanceolate, waved and ribbed, of a dark green colour, margined with white; the leaf stalks are stout, 6in. long, and broadly channelled.
Flowering period, June to August.
Funkia Sieboldii.
SIEBOLD'S PLANTAIN-LEAVED LILY; Nat. Ord. LILIACEAE.
This is a grand plant; the lily-like flowers alone are sufficient to commend it, but when we have them springing from such a glorious mass of luxuriant and beautiful foliage, disposed with a charming neatness rarely equalled, they are additionally effective. The illustration (Fig. 40) gives a fair idea of the form and dimensions of a specimen three years ago cut from the parent plant, when it would not have more than two or three crowns, so it may be described as very vigorous; and, as if its beauties were not sufficiently amplified by flowers and form of foliage, the whole plant is of a rich glaucous hue, rendering it still more conspicuous and distinct. It is herbaceous and perfectly hardy, though it comes from the much warmer climate of Japan, whence are all the species of Funkia. It is a comparatively new plant in English gardens, having been introduced into this country only about fifty years; still, it is pretty widely distributed, thanks, doubtless, to its exceptionally fine qualities. I know no plant more capable of improvement as regards size than this; if set in rich deep soil, it will in a few years grow to an enormous specimen. One so treated in my garden is 4ft. to 5ft. in diameter, and about the same height when the flower-stems are fully developed. I should, however, add that this is an unusual size, but it, nevertheless, indicates what may be done by high culture.
The flowers are produced on nude stems, 2ft. or 4ft. high, being arranged in somewhat short and irregular one-sided spikes; they spring singly from the axils of rather long bracts (see Fig. 40) and have long bending pedicels, which cause the flowers to hang bell fashion; their colour is a soft pale lilac, nearly white. Size, 1in. to 2in. long, and bell or trumpet shaped. They are of good substance, and last a long time in fine form. The leaves have radical stalks, nearly 2ft. long in well-grown specimens, gracefully bending and deeply channelled; they are from 8in. to 12in. long, and about half as wide, long heart-shaped, somewhat hooded, waved, distinctly ribbed, and evenly wrinkled; glaucous and leathery. The outer foliage is so disposed that the tips touch the ground; it is abundantly produced, forming massive tufts. The long fleshy roots denote its love of a deep soil; a moist but well-drained situation suits it, and manure may be used—both dug in and as a top dressing—with marked advantage. The natural beauty of this subject fits it for any position—the lawn, shrubbery, borders, beds, or rockwork can all be additionally beautified by its noble form; grown in pots, it becomes an effective plant for the table or conservatory. The flowers in a cut state are quaint and graceful, and the leaves are even more useful; these may be cut with long stalks and stood in vases in twos and threes without any other dressing, or, when desired, a few large flowers may be added for a change, such as a panicle of Spiraea aruncus, a large sunflower, or a spike or two of gladioli. Leaves so cut may be used for weeks; after they have become dusty they may be sponged, when they will appear fresh, like new-cut ones.
In the propagation of this plant certain rules should be observed, otherwise the stock of young plants will prove stunted and bad in colour. Do not divide any but strong and healthy clumps, taking care not to damage more roots than can be helped; do not divide too severely, but let each part be a strong piece of several crowns, and after this they should be allowed to make three years' growth in a good, rich, deep soil before they are again disturbed, and thereby the stock will not only be of a vigorous character, but always fit for use in the most decorative parts of the garden.
Flowering period, July to September.
Galanthus Elwesii.
ELWES'S GALANTHUS or SNOWDROP; Nat. Ord. AMARYLLIDACEAE.
This is a splendid species or variety, whichever it may be, said to be the finest of all the Snowdrops; it is a new kind and not yet much known. My impressions of it last spring were not in accordance with such reports, but I ought to add that, though the bulbs were fresh when sent me, they had only been planted less than a year, when they flowered somewhat feebly.
Flowering period, February and March.
All the Snowdrops may be propagated by seed or division of crowded clumps—after all the tops have died off is the proper time; the longer the delay, the worse for next season's bloom, as new root action sets in about that period.
Galanthus Imperati.
IMPERIAL SNOWDROP; Nat. Ord. AMARYLLIDACEAE.
I have only recently flowered this kind. It is said by Mr. W. Robinson to be double the size of G. nivalis, which estimate is probably correct, judging from the blooms which I have obtained. With me the bulbs seem either not to have a happy home, or they may have suffered from the vicissitudes of transport from the genial climate of Italy. The publisher of this book informs me that he flowered G. imperati the first year in the open borders, from some bulbs procured from Messrs. Collins Bros., and that the blossoms were highly scented, as of elder flowers.
Flowering period, February and March.
Galanthus Nivalis.
COMMON SNOWDROP, EARLY BULBOUS VIOLET, and FAIR MAIDS OF FEBRUARY; Nat. Ord. AMARYLLIDACEAE.
One of the most charming members of the British flora; a native of our fields and orchards, so beautiful as to be beyond description, and, fortunately, so common as to need none (see Fig. 41). It belongs to a noble order of bulbous plants, the genera of which are numerous, as are the species too, in perhaps an increased proportion. Comparatively few are hardy in our climate, and very few indeed are natives of this country, so that in this respect the Snowdrop, if not a rare flower, is a rare representative in our flora of the order Amaryllidaceae.
It may be useful to give a few of the better-known genera to which Galanthus is so nearly related: Amaryllis, Nerine, Crinum, Vallota, Pancratium, Alstroemeria, and Narcissus. The last-named genus is more nearly allied than any of the other genera mentioned; not only does it resemble the Galanthus in style, early period of bloom, and habit of becoming double, but also for the general hardiness of its species, a feature not usual in their order.
The literal meaning of the generic name is "Milk Flower." The title with such a pleasing reference was given by Linnaeus. The specific name—meaning white—may, for two reasons, seem unnecessary; first, because milk is white, and again, because no other than white-flowered species are known. All the three common names are happy ones: "Snowdrop" and "Fair Maids of February" are appropriate both to the season and a pretty flower; "Bulbous Violet" pleasantly alludes to its sweetness; all are poetical, as if this lovely flower had the same effect on the different minds of those (including Linnaeus) who first gave them. A dropped name for the Snowdrop was that of "Gilloflower"; Theophrastus, the father of natural history, gave it the name of "Violet" (Viola alba or V. bulbosa)—that would be 2100 years ago! The bulbs should be planted by thousands; they will grow anywhere and in any kind of soil; the demand for their blossom is ever increasing, and Snowdrops, as everybody knows, are always in place, on the grass, border, or window sill, or for table; they may be used as emblems of either grief or joy; they are sweetly pure and attractive, without showiness.
Flowering period, February to April.
Galanthus Plicatus.
FOLDED GALANTHUS; Nat. Ord. AMARYLLIDACAAE.
A species from the Crimea; compared with our native kind, it is larger in the grass, having also other, but very slight, points of difference. The main one is implied by its name, "plicatus," or folded; its leaves are furrowed, which causes it to have a folded appearance.
Culture and flowering period, the same as for the other species.
Galanthus Redoutei.
REDOUTE'S GALANTHUS; Nat. Ord. AMARYLLIDACEAE.
This is by far the most distinct form, having broad grass-green foliage. It is somewhat late in flowering (during March and April), and not so free as others.
Galax Aphylla.
Syn. BLANDFORDIA CORDATA; HEART-LEAVED GALAX; Nat. Ord. PYROLACEAE.
Nearly 100 years ago this charming little plant was imported from North America; still, it is rarely seen, notwithstanding that rock-gardens have long been popular. On rockwork it not only thrives well, but appears to great advantage. No rock-garden should be without it. It is a rare and beautiful subject, remarkably distinct and pleasing; it is perfectly hardy, also perennial and herbaceous; but its last-named characteristic should be qualified, inasmuch as the old leaves remain in good form and colour until long after the new ones are fully grown, so that there are always two sets of foliage. Viewed in this light, it may be called an evergreen plant; moreover, it is one of those plants which the artist can scarcely do justice to, for though the illustration (Fig. 42) depicts faithfully its neat habit and handsome foliage, the living plant makes a better impression. I said it was rare, but this is less in the sense of scarcity than because it is little known and seldom seen; it is also quite distinct from any other plant, and the only species of the genus.
Its milk-white flowers, which, though very simple, are richly effective, are produced on tall, nude stems, 18in. high, round, wiry, and nearly amber-coloured. They are arranged in a dense spike, 6in. to 8in. long; the corolla is 1/4in. across, and composed of five petals; the calyx has a short tube and five sepals; the leaves are heart-shaped, nearly round, evenly toothed, and sometimes glandular; of leathery substance, and somewhat stiff, smooth, shining, and richly veined or nerved. The leaves of various ages differ in colour; the old ones are dark green, conspicuously reticulated; the new, but perfectly-developed ones, are pale green, with a ray of yellowish-green next the edges; the growing ones are nearly red, and all the serrated edges are hemmed with a nearly scarlet line, always brightest at the points of the teeth. This finely-tinted foliage is elegantly disposed by means of the stalks, which bend in various ways; they vary in length from 4in. to 8in., and are all radical; they are round, wiry, and once grooved. The bloom lasts for several weeks in good form, and the foliage is always beautiful, more especially in the autumn, when it glows like polished mahogany. Such a plant can hardly fail to please when well grown, but it must be so developed.
This lovely plant certainly requires a little special treatment, but that is easy and simple; in fact, it scarcely can be called special. It may be put in a few words—damp, but not sour vegetable soil, and very slight shade. My specimen, from which the drawing was taken, is growing in a little dip at the base of a small rockery, below the level of the walk, which acts as a watershed; the soil is nearly all leaf mould—a small portion of loam, and I ought to add that there is a moderate quantity of small charcoal incorporated with it, which will doubtless assist in keeping the soil sweet. There cannot, therefore, be much difficulty in setting up these conditions; the charcoal may not be necessary, but an annual top-dressing with it will meet the case of such plants as grow in low damp situations. The propagation of this species is very easy in the case of well-grown clumps, which, when dug up in the autumn and thoroughly shaken, will come asunder into many small and well-rooted crowns; these only require to be replanted separately, under similar conditions to those by which they were produced. No attempt should be made to divide other than perfectly healthy clumps.
Flowering period, July and August.
Galega Officinalis.
OFFICINAL GOAT'S-RUE; Nat. Ord. LEGUMINOSAE.
A grand "old-fashioned" flower. It is 314 years since this plant was brought from Spain; it is perfectly hardy and herbaceous. Both it and its varieties are among the most useful subjects of the flower garden; they grow to shrub-like bushes, have elegant foliage, and an abundance of bloom, which continues until late autumn. Specimens have a clean and healthy appearance, and though they grow to the height of 4ft., they give no trouble, requiring neither tying nor supports. From their large quantities of flowers they are exceedingly gay; but it is for the handsome stems in a cut state that they should be most prized. These, cut 18in. long, and placed singly in pots or vases, are truly noble, more especially by gaslight.
As will be inferred from the order to which Galega belongs, the flowers are pea-flower-shaped, about 1/2in. or more long, and the same broad. They are of a pleasing, but undecided blue colour, arranged in long conical racemes, on stout, round stalks, as long as the leaves, which are pinnate, having a terminal odd one. The leaflets are evenly arranged in pairs, mostly in six pairs; they are each about 2in. long, lance-shaped, mucronate, entire, smooth, and glaucous. The floriferous character of the plant may be inferred from the fact that, after the raceme fades, there pushes from the axil a peduncle, which, in a short time, produces many other racemes.
G. o. alba, a variety of the above, grows 4ft. high, and is an abundant bloomer; flowers superb for cutting purposes. For culture, see G. Persica lilacina.
Flowering period, July to September.
Galega Persica Lilacina.
Nat. Ord. LEGUMINOSAE.
This is a lovely species of Galega imported little more than fifty years ago from Persia. Perfectly hardy; in general form it corresponds with G. officinalis. The following are its distinctions: More dense racemes of lilac flowers, a foot less tall, leaflets shorter and broader—in fact, oval, oblong, somewhat twisted or edged up in the arrangement, and often without the terminal leaflet.
The above Goat's-rues are of the simplest culture; they will do in any soil, but if they are liberally treated they will repay it. A fat loam and sunny situation are what they delight in. They may remain year after year in one position, but I find them to do better in every way if they are divided the second year; it should be done in summer, so that they can make a little growth in their new quarters before winter sets in. In order to carry out this, the older plants (I divide half my stock one year, the other half the year following) should be cut over near the ground, though they may be in full bloom. Divide the roots into several strong pieces, and replant them in soil deeply dug and where they are intended to flower; they will bloom finely the following season.
Flowering period, July to September.
Gentiana Acaulis.
GENTIANELLA; Nat. Ord. GENTIANACEAE.
A hardy, evergreen creeper, its creeping stems running immediately under the surface. This is a remarkably beautiful plant, and the wonder is that it is not grown in every garden. The most attractive features, when in flower, of this dwarf Gentian are its immensely large blooms and neat shining green foliage (see Fig. 43). It is easily identified, there being not another species like it, and certainly very few to equal it for beauty and service; it forms one of the best edgings for beds and borders. Many report that it is difficult to grow, which may be the case in some gardens from one cause or other, whilst in many places it runs like quick-grass.
Flowers, dark bright blue, large, long bell-shaped, but not drooping; tube, five-angular, nearly 3in. long; corolla, five-limbed, and an inch or more wide; the stems are seldom more than 3in. long, square, furnished with small opposite leaves, and terminated with one flower on each. That part of the foliage which sends up the flower is arranged in rosette form, the leaves being stout, flat, and acutely lance-shaped. Anywhere or everywhere may this subject be planted; it is always bright, even in winter, and when there are no flowers upon it it forms a rich covering for the otherwise bare ground; its blooms will each keep good a week. They are rarely produced in great numbers at one time, but the plants will continue for a long while to yield them sparingly.
I find G. acaulis to thrive well at the base of rockwork, as an edging to a flat bed, and in the gutters of the garden walks—it likes moisture. To me this is clearly proved by other plants, which, in all respects but one, are treated the same, the exceptional condition being that they are planted on the sloping face of rockwork, where they scarcely grow and never bloom. With reference to soil, rich or silky loam is best for it, but any kind, if sweet and retentive, will do. Its propagation may be effected by division of the rooted creeping stems after they have made four leaves. Very early in spring is a good time to do this, but neither these nor the old plant, if it has been much disturbed, will flower the same season after being so mutilated.
Flowering period, May to July.
Gentiana Asclepiadea.
SWALLOW-WORT-LEAVED GENTIAN; Nat. Ord. GENTIANACEAE.
A tall and beautiful alpine species from Austria, very hardy and herbaceous. It has long had a place in English gardens—fully 250 years—and is described by Parkinson in his "Paradise of Flowers." The tall stems are very showy, having an abundance of shining dark green foliage, amongst which nestle the large and bright purple-blue flowers; it is a subject that looks well at a distance, and, as a rule, flowers with that quality are of the greatest value for borders and cutting purposes.
It grows nearly 2ft. high; the stems are round, erect, short-jointed, and very leafy; the flowers are produced on a third of their length, they are stalkless, and spring from the axils of the leaves in pairs; the calyx is 1/2in. long, tubular, angled, and having fang-shaped segments; the corolla is also tubular and angled, somewhat bellied, the divisions being deeply cut and reflexed; the whole flower will be fully 11/2in. long. The inside of the corolla is striped with white and various shades of blue and purple. The leaves are 2in. long, oval, lance-shaped, distinctly ribbed, somewhat lobed at the base, and stem-clasping, which gives the pair of leaves a joined or perfoliate appearance; the nodes are short, or near together, the lower ones being the more distant, where also the leaves are much smaller; the foliage is a glossy dark green colour, the whole plant having a sombre but rich effect.
From the fact that the long stems are top-heavy and of a brittle character, a sheltered position should be given to this plant, or the wind will snap them off. It ought not to have stakes, as they would mar its good form. A fat loam and a moist situation will suit this Gentian to perfection, and it may be planted with other strong herbaceous things in the borders, where it should be allowed to grow to large specimens. It is one of the quickest growers of its genus, few species of which can be grown in too large quantities. When it is needful to increase this subject, it maybe done more readily than the propagation of some Gentians—the roots are more easily separated. It should, however, be carefully done, and early spring is the best time; or if the autumn should be a dry season and the tops die off early, it may be done then.
Flowering period, July and August.
Gentiana Burseri.
BURSER'S GENTIAN; Nat. Ord. GENTIANACEAE.
A hardy perennial species, of a bold but neat habit, while the flowers and foliage combine in rendering it a first-class decorative subject. It is a recent introduction, having been brought from the Pyrenees in 1820; it is seldom seen in flower gardens, where it certainly deserves to be.
Its flowers are not brilliant, but they are effective from their size, number, and persistency; they are produced in whorls on stout round stems 18in. high, but only on the three or four upper joints. Each flower is 11/2in. long, lemon-yellow, tubular, angular, having four to six segments, widely separated, and furnished with a membrane at each separation. The segments, and also the tube, are dotted with dark brown spots; each flower is tightly folded in a somewhat one-sided membranous calyx and borne erect. They occur in pairs mostly, but with several pairs in a whorl. They have very short pedicels, and the whorl is supported by a bract of stem-clasping leaves, cupped, and variously shaped, as ovate and beaked; there are also supplementary bracteoles. The leaves of the root very much resemble the plantain leaf, also that of G. lutea, having longish ribbed and grooved petioles or stalks; they are 5in. to 6in. long, and over 3in. broad, egg-shaped, entire, veined longitudinally, and slightly wrinkled; they are of a dark green colour, shining, and of good substance. The leaves of the stems, as already stated, are stem-clasping, and differ in shape. The flowers keep in good form for two or three weeks, and otherwise this rigid bright-foliaged Gentian proves very ornamental.
I find it to do well in vegetable soil in a moist quarter. Most of the members of this genus enjoy plenty of moisture at their roots, and this specimen is no exception. A flat stone will form a good substitute for a damp situation if placed over the roots; besides, such a method of growing this and others of the tall Gentians will allow of their being planted on rockwork, or otherwise, near the more frequented walks, where they must always prove pleasing from their bold and shining foliage, to say nothing of their striking flowers. The propagation of this species should be effected by division of the roots, which are very strong. Each crown should have as much of the more fibrous roots retained as possible, and the parts to be severed should be cut with a very sharp knife; it also ripens seed plentifully.
Flowering period, June to August.
Gentiana Cruciata.
CROSS-LEAVED GENTIAN; Nat. Ord. GENTIANACEAE.
An interesting species from Austria, and one of the "old-fashioned" plants of English gardens, having been cultivated in this country for nearly 300 years. Gerarde gives a faithful and full description of it, which I will quote: "Crossewoort Gentian hath many ribbed leaues spred upon the ground, like unto the leaues of sopewroot, but of a blacker green colour; among which rise vp weak iointed stalks, trailing or leaning towarde the grounde. The flowers growe at the top in bundels, thicke thrust togither, like those of sweete Williams, of a light blew colour. The roote is thicke, and creepeth in the grounde farre abroade, whereby it greatly increaseth." Its height seldom exceeds 10in., and it is to be commended because it is one of the Gentians that are easily grown, and is handsome withal. It may be planted in either vegetable or loamy soil—the common border seems to suit it; it spreads much faster than any of the other Gentians I know, with the exception of G. acaulis, and it is in broad masses one sees it to greatest advantage. Propagated by division any time.
Flowering period, June and July.
Gentiana Gelida.
ICE-COLD GENTIAN; Nat. Ord. GENTIANACEAE.
This species comes from Siberia, and has been grown in this country for nearly eighty years. It is a very beautiful species, the whole plant being handsome; it grows nearly a foot high.
The flowers are produced in terminal clusters, one large flower being surrounded by a whorl of smaller ones; they are of a rich purplish-blue inside the corolla, which is rotate; the segments (mitre-shaped) and the spaces between are prettily furnished with a feathery fringe; the wide tube is also finely striped inside; the calyx is tubular, having long awl-shaped segments; the stems are procumbent, firm (almost woody), short jointed, and thickest near the top. The leaves are of a dark shining green colour, from 11/2in. to 2in. long, smallest at the root end, and finishing next the flowers with the largest, which are lance-shaped, the lower ones being heart-shaped; they are closely arranged in pairs, are sessile, and at right angles with the stem.
It seems to enjoy a shady damp corner in rockwork, where its distinct forms and neat habit appear to advantage. It should be planted in vegetable soil, such as peat or well-decayed leaves mixed with sand. It cannot endure drought at the roots. It is a slow-growing plant, but very floriferous; the flowers last fully a fortnight in good form, the weather, however rough or wet, seeming to have no effect on them. In a cut state it is exquisite, but those who properly value the Gentians, especially the slow growers, will hardly care to cut away the stems, as, by doing so, not only will the plant be checked, but next year's growth will prove reduced in both number and vigour. It is propagated by root division when in a dormant state. I have also successfully transplanted this kind after it has made considerable growth, but the roots have been carefully guarded against dryness.
Flowering period, June to August.
Gentiana Verna.
SPRING ALPINE FELWORT; Nat. Ord. GENTIANACEAE.
A native evergreen creeper. This plant has many synonymous names in old books. It is now, however, well known by the above Latin name. Let me at once say that it is a matchless gem. Its flowers are such as to attract the notice of any but a blind person. It is said to be rare now in this country, still, I think it is far from being extinct in its wild state. Be that as it may, it is fortunate that it can be easily cultivated, and nothing in a garden can give more pleasure. Its flowers are blue—but such a blue! the most intense, with a large and sharply defined white eye, and though only 1/2in. across, one on each stem, and 3in. high, they are grandly effective. It has a tubular, angled calyx; corolla five-cut. The leaves are oval, nearly 1in. long, and half as broad; dark shining green and of leathery substance. The radical leaves are crowded into a nearly rosette form.
By many this Gentian is considered difficult to grow, but if a proper beginning is made it proves to be of the easiest management. Very suitable places may be found for it in, not on, rockwork, where good fat loam forms the staple soil; little corners, not above the ground level, but on, or better still, below the ground level, are sure to meet its requirements; on the edge of a border, too, where moisture collects in the small gutter, has proved a suitable position for it. But, perhaps, the most successful way of growing it is in pots, for, as with Trientalis Europa and other root creepers, when so treated more compact specimens are obtained. It is important to begin with properly-rooted plants, the crowns of which are often 2in. to 3in. below the surface; from these spring the numerous, bare, yellow, wiry stems, too often taken for roots, whereas the main roots are still deeper, very long for so small a plant, and furnished with silky feeders. Good crowns potted in rich fibrous loam and plunged in sand, fully exposed, with an unstinted supply of water, is the substance of the simple treatment my plants receive the year round; they are still in the 3in. and 4in. pots in which they were placed three years ago, and during spring they are covered with flowers. When a pot is lifted out of the sand in which it is plunged, the fine long silky roots are seen to have made their way through the hole. Spring is the best time to plant.
Flowering period, April to June.
Geranium Argenteum.
SILVERY CRANE'S-BILL: Nat. Ord. GERANIACEAE.
A hardy perennial alpine from the South of Europe, introduced in 1699. It is, therefore, an old plant in this country, and is one of the gems of the rock garden; very dwarf, but effective, as may be seen by the illustration (Fig. 44). The foliage is of a distinct and somewhat conglomerate character, besides being of a silvery-grey colour. Well-grown specimens of this charming Crane's-bill look remarkably well against dark stones. Its flowers are large for so small a plant, and wherever it finds a suitable home it cannot fail to win admiration. In borders of rich soil it is grown to the height of about six inches, but in drier situations, as on the upper parts of rockwork, it is more dwarf.
The flowers are fully an inch in diameter when open, cup-shaped, and striped in two shades of rose colour; the unopened flowers are bell-shaped and drooping; they are borne on long naked pedicels, bent and wiry, oftentimes two on a stem; calyx five-cleft, segments concave; petals five, equal and evenly arranged. The leaves are produced on long, bent, wiry stalks, the outline is circular, but they are divided into five or seven lobes, which are sub-divided and irregular, both in size and arrangement; they have a silky appearance, from being furnished with numerous fine hairs or down. The plant continues to flower for many weeks, but, as may be judged, it is, otherwise than when in flower, highly attractive. To lovers of ornamental bedding this must prove a first-rate plant. As an edging to beds or borders of choice things it would be pleasingly appropriate, and, indeed, anywhere amongst other dwarf flowers it could not be other than decorative.
It thrives well in a good depth of loam, its long tap-roots going a long way down. If, therefore, it is planted on rockwork, suitable provision should be made for this propensity. The propagation of the plant is not so easy, from the fact that it makes large crowns without a corresponding set of roots, and its seed is scarce and often taken by birds before ripened. Moreover, the seedlings do not always come true; still, it seems the only mode of propagation, unless the old plants have plenty of time allowed them to spread and make extra roots. Latterly I have gathered the seeds before the capsules burst—in fact, whilst green—and, after carrying them in the waistcoat pocket for a few days, they have been sown in leaf soil and sand, and germinated freely. When the seedlings have made a few leaves the deteriorated forms may be picked out readily.
Flowering period, May to July.
Gillenia Trifoliata.
Syn. SPIRAEA TRIFOLIATA and S. TRILOBA—THREE-LEAVED GILLENIA; Nat. Ord. ROSACEAE.
A hardy herbaceous perennial from North America, imported in 1713. The main features about this plant are its elegant form and rich tints. The illustration (Fig. 45) may give some idea of the former quality, but to realise the latter the reader should see a living specimen in the form of a bold clump. There is a wild beauty about this subject which it is not easy to describe; as a flower it is insignificant, but the way in which the flowers are disposed on the slender stems, blending with a quaintly pretty foliage, neither too large nor dense, renders them effective in their way. It is, however, only as a whole that it can be considered decorative, and it should be well grown.
Although most nearly related to the spiraeas the distinctions from that genus are very marked, notably the very slender stems and large flowers, which are produced singly on rather long-bending pedicels, almost as fine as thread, and, like the stems, of a bright brown (nearly ruddy) colour. The flowers form a lax panicle, interspersed with a little foliage. The calyx is a bright brown colour, rather large and bell-shaped. It contrasts finely with the five long, narrow petals, which are white, tinted with red; they are also irregular in form and arrangement, somewhat contorted. The leaves, as implied by the specific name, are composed of three leaflets; they have very short stalks, and the leaflets are all but sessile, lance-shaped, finely toothed or fringed, ribbed, and somewhat bronzed. Perhaps it is most useful in a cut state; the sprays, even if they have but one or two flowers on them, are charming for vase work. I may say the calyx is persistent, and after the petals have fallen they not only increase in size, but turn a fine red colour, and so render the sprays additionally effective.
To grow this plant well it should have a deep soil; it also loves moisture, and, as already hinted, partial shade; it is a steady grower, far from rampant, like the spiraeas. This is a capital subject to grow near or under "leggy" shrubs and trees, where, in semi-shade, it is not only at home, but proves very attractive. It may be propagated by division, the best time being early in the year, just before growth commences.
Flowering period, June to August.
Gynerium Argenteum.
PAMPAS or SILVERY GRASS; Nat. Ord. GRAMINEAE.
This handsome grass is well known, at least, its feathery plumes are, from the fact of their being imported largely in a dry state for decorative purposes. It has not been grown long in this country, and, perhaps, it is not generally known that it endures our climate as an outdoor plant; in most parts of Great Britain, however, it proves hardy. As far north as Yorkshire I have seen it in the form of specimens 8ft. high; my own examples are yet young—two and three years old—and are only just beginning to flower, at the height of 3ft. to 4ft., diameter about the same. It is a native of South America, occurring mostly on the prairies; it is also found in other parts where there are swamps and high temperatures. This would lead us to have doubts as to its suitableness for English gardens, but facts prove it to have elastic qualities in this respect. It proves at all times to be a noble ornament in gardens of moderate size.
In its growing or green state it is a distinct and pleasing object, but it is at its greatest beauty when it has ripened its tall and silky plumes, which glisten in the sunshine and are of a silvery-grey colour, and when also the very long and narrow grass has become browned and falls gracefully, more or less curling under the tufts. All its parts are persistent, and, as a specimen of ripe grass, it is not only ornamental in itself, but it gives a warm effect to its surroundings during winter. Under favourable conditions it will grow 10ft. or 12ft. high, but it is seldom that it attains a height of more than 8ft. or 9ft. As an illustration (Fig. 46) is given, further description is not needed. I may add that if it is not "laid" by heavy snows, it keeps in good form until the new grass begins to grow in the following spring.
I find it to do well in light earth, well enriched with stable manure, the soil having a more than ordinary quantity of sand in it; the position is such as can have a good supply of moisture, being near walks that drain to it. In stiffish loam a strong clump was planted three years ago, but it has never looked healthy. The best positions for it are well-prepared shrubbery borders; there it contrasts finely with the greenery, and receives some protection from the high winds. It may be increased by division of healthy roots, when the grass is ripe, but it ought not to be cut off.
The plumes appear in August, and will keep in good condition till the weather changes to a wintry character.
Harpalium Rigidum.
Syn. HELIANTHUS RIGIDUS—RIGID SUNFLOWER; Nat. Ord. COMPOSITAE.
One of the most effective and beautiful flowers to be seen in autumn; it would be hard to mention another at any period of the year that gives more satisfaction and pleasure than this does, either as a decorative plant or a cut flower. A bold specimen, 4ft. through, is truly fine, and not only those who seldom visit a garden, but amateurs well versed in flowers, are alike charmed with its rich and stately blossoms. Most people know what a Sunflower is; many of them are coarse and almost ugly; but though the present subject is of the family, it is supremely distinct; it is without the formal character in its ray, and also the herby leafiness of many of its genus, its large, clean, shining, golden flowers, mounted on slender, ruddy, long, and nearly nude stalks, not only render it distinct, but impart an elegance to this species, which is all its own. It grows 4ft. high, is a comparatively new kind in English gardens, and comes from North America; still, it has become widely known and appreciated, in fact a universal favourite, so much so that, although it increases fast, the demand for it is not yet satisfied; it is, doubtless, a flower for every garden.
The flowers are 4in. across, glistening golden yellow, and formed of a deep ray and small disk; the florets of the ray are 11/2in. long and more than 1/2in. broad, they are incurved at their points, but reflexed at their edges, and are handsomely ribbed or pleated; they are arranged in two or three rays in each flower, and irregularly disposed; the florets, being well apart, not only seem to give the bloom body, but also an artistic informality and lightness. The florets of the disk are chocolate colour, whence issue twirled filamentary forms, which impart to the centre of flower the appearance of being netted with a golden thread. The scaly involucre is formed of numerous small members of a dark olive-green colour, neatly arranged and firmly clasping the whole flower. The pedicels are long, round, covered with short stiff hairs, and thickened at the involucre; the stems are very rough, rigid, hard, and brown or ruddy on the sunny side, sometimes twisted and nude, with the exception of a solitary rudimentary leaf. The main stems have many axillary branches. The leaves of the root are few, 5in. or 6in. long, and oval. Those of the stems more lance-shaped, sessile, and slightly dentate, or toothed, lessening in size as they get higher; all the leaves are very thick, three-veined, and remarkably hispid, being almost as coarse as sandpaper to the touch. I have also observed another peculiarity about the leaves, when they have been taken from the plant for an hour or more, i.e., they have a most elastic property. Very often the leaves may be seen in trios, whence spring three side branches, surrounding the upright and central one. The habit of the whole specimen is very rigid, with the exception of the flowers, which are slightly nodding; the tallest growths need no stakes, and the species enjoys a happy immunity from insect pests, probably by reason of its hispid character. As already stated, as a garden subject this is one of the most useful; it shows grandly in front of evergreens, and associates well with lilies. In borders of tall perennials, or in conspicuous but distant situations, such as are visible from the doors or windows of the house, or as isolated clumps, on or near the lawn, this fine Sunflower may be planted with satisfactory results; in fact, it cannot be planted wrong, provided it is kept away from small subjects. In a cut state it is of such value that it cannot be overpraised—a branch with four fully blown flowers and others nearly out, requires no assistance as a table decoration. Its blooms have the quality of keeping clean, doubtless from the smoothness of the florets.
The cultural requirements are few. Any garden soil will do for it, but if deeply dug and well enriched with stable manure, so much the better; it should have a fairly open situation; it is not only a Sunflower in name and form, but it enjoys sunshine. It is self-propagating, and runs freely at the roots, immediately under the surface; the thick stolons form knobby crowns at their extremities, out of and from under which the roots issue, going straight and deep down, and so forming an independent plant.
Flowering period, August and September.
Hedera Conglomerata.
CONGLOMERATE IVY; Nat. Ord. ARALIACAE.
I do not introduce this as a flowering subject, but as a dwarf ornamental shrub; it differs so much from all other species and varieties of Ivy, and is so beautiful withal, that I trust no further apology is needed for giving it a place amongst decorative plants and shrubs. I have not been able to learn its habitat or origin; its stunted tree-like shape, together with other peculiarities, would indicate that it is a species; be that as it may, it has long had a place in English gardens, and yet it is seldom met with—it would be hard to explain why. On a bit of rockwork I have grown a specimen for nearly five years, and it was an old shrub when planted, yet it is not more than 2ft. in diameter and 1ft. high. It is much admired, and many notes have been taken of it. For rockwork, it is one of the best dwarf evergreen shrubs I know.
It has very small leaves, densely arranged in flat or one-sided wreaths. They seldom exceed 1in. in diameter, and are of various forms, as heart-shaped, sagittate, oval, tri-lobed, and so on. Some are notched, others slightly toothed, but many are entire. All are waved or contorted, wrinkled and thickened at the edges, where the younger leaves show a brown line; the under sides are pale green, and furnished with short stiff brown hairs, as also are the stout leaf stalks. The upper side of the foliage is a dark glossy green, with shadings of brown. In substance the leaves are leathery, inclining to stiffness. The stunted branches have a cork-like appearance as regards the bark, are diffuse, curiously bent, and sometimes twisted loosely together. It is of slow growth, more especially in the upward direction, and though provision may be made for it to cling and climb, and it has also well-formed roots on the branchlets, still, it assumes more the tree-shape. I never saw or heard of its flowering, much less that it ever produced seed; if it does not seed we are not only deprived of an ornamental feature belonging to the genus from the absence of berries, but it proves that it is only a variety of some species.
It may be grown in any kind of sandy soil, and nothing special whatever is needed. An open sunny situation will favour its form and colour of foliage; under trees I have found it to produce larger leaves of plainer shape and more even colour. During the winter it becomes a conspicuous object on rockwork, where it seems most at home. It may be propagated by cuttings, and spring is a suitable season to lay them in; in well dug light soil they soon make plenty of roots.
Helianthus Multiflorus.
MANY-FLOWERED SUNFLOWER; Nat. Ord. COMPOSITAE.
This fashionable flower is glaringly showy. Still, it is not wanting in beauty; moreover, it belongs to an "old-fashioned" class, and is itself a species which has been grown for nearly 300 years in English gardens. It was brought from North America in the year 1597, and during the whole of its history in this country, it can hardly ever have been more esteemed than it is to-day; it is very hardy, and in every way a reliable subject. Everybody knows the Sunflower, therefore no one will care to read a description of it; still, one or two remarks may, perhaps, be usefully made in the comparative sense, as this is a numerous genus. Many of the Sunflowers are annuals, to which this and others of a perennial character are much superior, not only in being less trouble and not liable to be out of season from mismanagement in sowing and planting, as with the annual sorts, but from the fact that their flowers are of better substance and far more durable; they are also less in size and more in number—two points of great gain as regards their usefulness as cut bloom. They are, besides, better coloured, and the flowering season more prolonged. Well-established specimens, two or three years old, will, in average weather, last in good form for fully six weeks. The colour (yellow) is common to the Sunflowers. This species has flowers which vary much in size, from 2in. to 6in. across, and they are produced on stems 3ft. to 6ft. high, well furnished with large heart-shaped leaves of a herb-like character, distinctly nerved, toothed, and rough.
Flowering period, August and September.
H. m. fl.-pl. is, of course, the double form of the above, the disk being represented by a mass of florets considerably shorter than those of the ray proper. The flowers are not produced in such large numbers as with the typical form, neither does the plant grow so tall, but the foliage is a little larger; these constitute all the points of difference which I have noticed. These forms of Sunflower are very effective—nowhere, perhaps, so much as amongst shrubs. The plants lift well, carrying a good ball that facilitates their being placed in pots even when in bloom, when, as I have lately seen, they may be used in a most telling manner with potted shrubs in large halls, corridors, and public buildings. In such places they get no sun to make them droop, and a good watering keeps them as fresh as if they had not been disturbed. Of the usefulness of this flower in a cut state nothing whatever need be said—who has not tried it? Doubtless, when it becomes unfashionable it will have fewer patrons, but it will be the same flower, richly beautiful—aesthetic. No special culture is needed, any kind of garden soil will suit it; if well enriched, all the better. Any situation will do but one too densely shaded. Propagated by splitting the roots after the plants have done flowering, or in spring.
Flowering period, August and September.
Helianthus Orygalis.
GRACEFUL SUNFLOWER; Nat. Ord. COMPOSITAE.
Yet another Sunflower, and one, too, of the common yellow colour, and not otherwise attractive, as may be seen by the illustration (Fig. 47)—of course, I am now referring to the flower only. There are, however, features about this species which all must admire; stems 7ft. high, furnished with bright foliage, in the manner indicated, are not mean objects, even if topped with but a common yellow composite. This is a native of North America, and of recent introduction; it is a distinct species, and for foliage a prince among its fellows. I know not another to nearly approach it, H. angustifolius being perhaps the nearest, but that species has never with me proved of more than a biennial character, and its leaves, though long and narrow, are irregular and herby.
The flowers need not be further described beyond saying that they are borne on short side shoots, near the top of the main stems, but they harmonise with the general arrangement of foliage, and, indeed, from their bract-like leafiness, somewhat enrich it. This is one of the latest-blooming Sunflowers. The leaves are 5in. to 8in. long, and 1/2in. to 1in. wide, the lower half on the stems droop, though they are of good substance; the upper half bend gracefully, and, from their close arrangement, all but hide the stem. At the axils of the larger leaves, tufts of smaller (much smaller) leaves appear, causing the long stems to be top-heavy. Still, they wave and bend during the strongest winds without supports or damage. It will be seen that the usefulness of this plant consists in its distinct form and tallness, and that it is effective is without doubt. Among low shrubs, or with other tall things, will prove suitable quarters for it.
Any kind of soil will do, shelter from the wind being the most important, and perhaps the only point to study when planting. It is propagated by root divisions when the tops have withered.
Flowering period, September and October.
Helleborus Abchasicus.
ABCHASIAN HELLEBORE; Nat. Ord. RANUNCULACEAE.
This is a native of the Caucasus, and in this climate, where it has been cultivated about fifteen years, it retains its foliage through the winter in a green state. It is a free grower, and flowers well, having a somewhat slender habit. It is sometimes described as having green flowers, but more often as having purple ones. It may be useful to remember that there are varieties, and it is likely that, even in the so-called green flowers, traces of purple will be seen. Not only is it a fact that this species, like H. purpurascens and H. niger, is far from fixed as regards depth of colour, but it is said to be one of the parent forms of some of the fine hybrids. These considerations may help to reconcile the apparently conflicting descriptions as regards bloom colour.
The flower stems are 12in. to 18in. high, distantly forked twice, and of a purplish colour. The flowers are produced in threes and fours on each of the branchlets, are inclined to purple, over 2in. across, and nodding; sepals oval, waved, and set well apart at the outer ends; petals scale-like, green, and numerous; anthers a beautiful delicate yellow; leaves of the flower stems few, small, and of irregular form, notched, finely serrate, and of a purplish-green shade; in their young state more especially does the purple prevail on the under surface—they are, in fact, nearly the colour of the flowers. The radical leaves are many, nearly a foot in diameter, of a dark green colour, and leathery substance; the leaflets are rather distant from each other, forming a noble pedate leaf; they are somewhat one-sided, slightly waved, sharply and regularly toothed nearly all their length. From this description it will be inferred that this is one of the most distinct species, and such is truly the case. Moreover, it has a bold and rich effect. The older radical foliage, with its long stalks, is for the most part spread on the ground, when the new erect flower stems, furnished with small leaves and nodding buds and blossoms, all of a shining purplish colour, form a peculiar but pleasing contrast, not nearly so marked in any other species with which I am acquainted. There is a variety called H. A. purpureus, in allusion to the colour of the flowers being a little more purple.
This Abchasian species and its varieties are not widely distributed; they are to be obtained, and need no longer be found only in rare collections. It is desirable in every way for the garden, where it forms a most ornamental object during winter. Its flowers last for four or five weeks, and in a cut state they form rich companion bloom to the white Christmas Rose.
A good fat loam suits them; the position should be rather shady and moist, but by all means well drained. A top dressing of good rotten manure, after all have done blooming, about the end of March, is a great help to them. All the Hellebores may be easily increased by root divisions, but the stock should be strong and healthy. Roots affected with the least rot or canker should be discarded, as from their slowness of growth they will not be worth garden space. Seed may also be raised, but unless sown as soon as it is ripe germination is less certain, and always slower in proportion to the length of time it has been kept dry. I may add that, in February (1883), I noticed a pot, sown with Hellebore seed in February of 1880; a few were just pushing through the mould. The seed was sold to me as the produce of 1879. Since 1880 I have sown seed ripened on plants that were bloomed for indoor decoration, it being ready about February. From this I had nice little plants in less than twelve months. But by seed the process of propagation is slow, and not advisable unless the object is to obtain new varieties—a very easy matter, by the way, with this family, if the simple rules of cross-hybridising are applied. |
