Mint.—May be grown in any garden soil. It is increased by runners, which, if not held in check, become very troublesome. The roots may be confined by means of tiles or slates. Flowers in July. Height, 11/2 ft.

Mistletoe.—Raise the bark of an apple, pear, or oak tree on the underneath part of a branch and insert some well-ripened berries, then tie the bark down neatly with raffia or woollen yarn. If the berries were inserted on the top of the branch the operation would result in failure, as the birds would devour them.

Mitella Diphylla.—A hardy perennial which bears slender racemes of white flowers in April. It makes a pretty rock plant, delights in a peat soil, and is increased by division of the root. Height, 6 in.

Moles.—These pests may be destroyed by placing in their runs worms that have been kept for some time in mould to which carbonate of barytes has been added.

Monardia Didyma (Oswego Mint, or Horse Balm).—See "Bergamot."

Monetia Barlerioides.—An ornamental shrub, suitable for the greenhouse or stove. It requires to be grown in loam and peat, and may be increased by cuttings planted in sand, under glass, in a bottom-heat. Height, 3 ft.

Monkey Flower.—See "Mimulus."

Monkey Puzzle.—See "Araucaria."

Monk's-hood.—See "Aconite."

Montbretia.—Very graceful and showy plants. The flowers, which are like small Gladioli, are produced on long branched spikes and are excellent for cutting. Plant 3 in. deep and 2 in. apart in sandy loam and leaf-mould. The corms should never be kept long out of the ground, as they shrivel, and weak growth and few flowers are the result. Though they are hardy it is well to give them a covering of litter in winter. They may also be grown in pots. Height, 2-1/2 ft.

Moraea Iridioides.—These plants flower in May, and require the same treatment as Ixias.

Morina (Whorl Flower).—An ornamental hardy perennial, which is seldom met with. It forms rosettes of large, deep green, shiny foliage and stout spikes of rose-coloured flowers in whorls, which make it one of the most attractive of Thistles. It likes a rich, light soil, is increased by seed sown in the autumn, also by division in August, and flowers in July. Height, 21/2 ft.

Morisia Hypogaea.—This is a pretty hardy perennial for rock-work. It flowers in May, and is raised from seed sown as soon as it is ripe. Height, 2 in.

Morna Elegans.—Beautiful half-hardy annuals. For early flowering sow the seed in September: for later blooms sow in February in slight heat, pot off, affording good drainage to the plants. They are very sensitive to cold, and should not be placed out of doors before the end of May. Avoid over-watering, as this would prove fatal to them. The soil should be light and sandy. Those sown in September will bloom in the greenhouse in May; those sown in February will flower in the open in the autumn. Height, 11/2 ft.

Morning Glory.—See "Convolvulus."

Morrenia Odorata.—A good twining plant for the greenhouse, producing fragrant cream-coloured flowers in July. It will grow in any good loamy soil, and may be increased by cuttings. Height, 3 ft.

Moss.—To eradicate moss from fruit-trees wash the branches with strong brine or lime water. If it makes its appearance on the lawn, the first thing to do is to ensure a good drainage to the ground, rake the moss out, and apply nitrate of soda at the rate of 1 cwt. to the half-acre, then go over the grass with a heavy roller. Should moss give trouble by growing on gravel paths, sprinkle the ground with salt in damp weather.

Mountain Avens.—See "Dryas."

Muhlenbeckia Complexa.—A very decorative climber, hardy in nature but requiring a good amount of sunshine to make it bloom. A well-drained, sandy soil is best for its growth, and it can be increased by cuttings of hardy shoots taken early in summer. Height, 6 ft.

Mulberries.—Any good soil will grow the Mulberry. The tree is hardy, but the fruit wants plenty of sunshine to bring it to perfection. It may be propagated by cuttings of wood one year old with a heel two years old attached. The only pruning necessary is to keep the branches well balanced. Autumn is the time to do this, not forgetting that the fruit is borne on the young wood. When grown in tubs or large pots in the greenhouse the fruit attains the perfection of flavour. In addition to the Large Black and the White (Morus Alba) the New Weeping Russian White may be recommended.

Mulching.—See "Soil."

Muscari.—See "Hyacinthus."

Muscari Botryoides.—See "Hyacinthus."

Mushrooms.—Take partially dry horse manure and lay it in a heap to ferment. Turn and mix it well every few days, and when well and equally fermented, which will be from ten to fourteen days, make it into a bed 4 ft. wide and 2 ft. deep, mixing it well together and beating or treading it firmly. When the temperature of the bed falls to 75 degrees, or a little under, the spawn may be inserted in pieces about the size of a walnut, 2 in. deep and 6 in. apart. Now give a covering of loamy soil, 2 in. deep, and beat it down evenly and firmly. Finish off with a covering of clean straw or hay about 1 ft. thick. Water when necessary with lukewarm water; but very little should be given till the Mushrooms begin to come up, then a plentiful supply may be given. They may be grown in any warm cellar or shed, and usually appear in from four to six weeks after planting.

Musk (Mimulus Moschatus).—A well-known sweet-scented, half-hardy perennial, well adapted for pot culture. A moist, shady position is most congenial to it when placed in the border. Seed sown in autumn make fine, early-flowering greenhouse plants. For summer blooming the seed is sown early in spring, under a frame or hand-glass, at a temperature of from 55 to 60 degrees. It is readily propagated by division. Height, 6 in.

Mustard and Cress.—For sowing in the open choose a shady border, make the surface fine and firm, and water it well before putting down the seed. Let the seed be sown thickly at intervals of seven or fourteen days from March to September. As the Cress does not germinate so quickly as the Mustard, the former should be sown four days before the latter. The seed must not be covered, but simply pressed into the surface of the soil. Keep the ground moist, and cut the crop when the second leaf appears. For winter use it is best sown in boxes and grown in a frame, the seed being covered with flannel kept constantly moist. This may be removed as soon as the seed germinates. Gardeners mostly prefer to grow it through coarse flannel, to avoid the possibility of grit being sent to table. The curled leaf Cress is the best, and the new Chinese Mustard is larger in leaf than the old variety, and is very pungent in flavour.

Myosotis (Forget-me-not).—The perennial varieties of these beautiful plants grow best in moist places, such as the edges of ponds or ditches; but they also do well in pots among Alpine plants. Most of them may be increased by root division, and all of them by seed. The annuals like a dry, sandy soil, and are grown from seed sown in March. They flower in June or July. Height, 6 in.

Myrica Gala (Candleberry Myrtle).—This hardy deciduous shrub is very ornamental, and its foliage is scented like the myrtle. It will grow in light, rich soil, but thrives best in peat, and may be increased by seeds or layers. May is its flowering time. Height, 4 ft. M. Cerifera is treated in precisely the same manner. Height, 6 ft.

Myrsiphyllum Asparagoides.—See "Smilax."

Myrtle (Myrtus).—Will strike readily if the cuttings be placed in a bottle of water till roots grow, and then planted; or young cuttings will strike in sandy soil under a hand-glass. They succeed best in a mixture of sandy loam and peat and on a south wall. Near the sea they prove quite hardy. Height, 6 ft.

N

Narcissus.—See "Daffodils."

Nasturtiums.—These are among the most useful of our hardy annuals, producing a display of the brightest of colours throughout the entire summer. The tall-growing climbers make a gay background to a border, and are equally valuable for trellis-work, while the dwarf varieties are first-class bedding plants, and of great service for ribboning. The seeds may be sown in pots in September or in the open ground early in spring. A light sandy or gravelly soil is the best to produce a wealth of bloom. Height, 6 ft. and 1 ft.

Nectarines.—Require the same treatment as the Peach. In fact, the Nectarine stone sometimes produces a Peach, and a Peach stone often produces a Nectarine. Fairchild's, Humboldt, Lord Napier, and Red Roman are useful varieties. They should stand 20 ft. apart.

Neilla.—These shrubs thrive in ordinary soil, and are increased by cuttings of the young wood. They flower in July. N. Torreyi bears white Spiraea-like flowers, which are very effective. Height, 6 ft.

Nemesia.—A most beautiful half-hardy annual of the Antirrhinum class. Sow the seed early in spring on a hotbed, and plant out in May in rich, light soil. Cuttings of the young wood will strike under glass. Height, 1-1/2 ft. to 2-1/2 ft.

Nemophila.—Pretty, neat, and compact hardy annuals, well worth cultivating. They succeed best in a moist and shady situation, delight in peat or vegetable mould, and when grown in circles are very striking. If wanted to flower early, sow the seed in autumn, or on a hotbed in spring; and if required for late blooming, sow in the open in March. Treated thus they flower from June to September. Height, 1 ft.

Nepeta Glechoma Variegata.—A very useful plant for hanging baskets. It can be trained as a pyramid or allowed to hang down; in many cases it is employed as edgings. It is of easy culture, and does well as a window plant or in a cool greenhouse. The soil should be light and dry. It flowers in July, and may be increased by root-division.

Nerine Sarniense.—See "Guernsey Lily."

Nertera Depressa (Coral Berry).—This pretty Moss-like plant is fairly hardy, and is eminently suited for a sheltered position on the rockery. The soil should consist of leaf-mould and sand, and overhead sprinkling with soft water is very beneficial. In cold districts it is better to grow it in the greenhouse. The flowers are produced in July, succeeded by orange-coloured berries. It is easily increased by dividing it early in the spring. Height, 3 in.

Neuvusia Alabamensis.—A tamarix-like shrub, bearing clusters of white flowers early in spring. Will grow in any soil or situation. Increased by cuttings placed in sand under glass.

Nicotiana (Tobacco Plants).—Very showy half-hardy annuals. N. Affinis bears long, tubular, sweet-scented, white flowers in July, and grows to the height of 3 ft. N. Virginica produces immense leaves and pink flowers, and the plants are 4 to 5 ft. high. The seed is sown on a hotbed in spring, and when the second or third leaf appears the plants are put into small pots and placed in a frame till the end of May, when they are transferred to the border.

Nierembergia (Cup Flowers).—These elegant half-hardy annuals grow well in any light soil, but prefer a mixture of sandy loam and leaf-mould. Sow the seed in March or April in slight heat, harden off, and plant out in May as soon as all fear of frost is over. They flower in July. Height, 9 in. to 1 ft.

Nierembergia Rivularis.—This herbaceous plant is of a creeping nature; it has deep green ovate foliage and large saucer-shaped white flowers. It needs a moist position, and is increased by division. The bloom is produced throughout June, July, and August. Height, 3 in.

Nigella.—These hardy annuals, a species of Fennel-flower, are both curious and ornamental. Perhaps the best known among them is N. Hispanica, or Love-in-a-Mist. They only require sowing in the open in spring—but not before the middle of March—to produce flowers in July and August. Height, 9 in. to 2 ft.

Night-scented Stocks.—See "Mathiola."

Nolana.—Hardy annuals that are suitable for the border, as they are very showy when in flower. The seed should be sown in spring on a gentle hotbed, and the plants transferred to the garden about the middle of May. N. Atriplicifolia may be sown in the open in the autumn. They flower in July and August. Height, 6 in. to 2 ft.

North Borders, Plants suitable for.—Hardy Camellias, Chrysanthemums, black and green Tea Plant, Rhododendrons, Ferns, Red Currants, Morello Cherries, and spring and summer cuttings of all sorts.

Nuttallia.—This early-flowering shrub is only hardy in the south and south-west of our country. It requires a light, rich soil, and may be increased by division. Racemes of white flowers are produced during February and March. Height, 2 ft.

Nycterina.—Exquisite little half-hardy plants, suitable for pots or rock-work. The seed should be sown early in spring on a gentle hotbed, and the young plants transferred to the pots or open ground at the end of May, using a light, rich soil. Height, 3 in.

Nymphaea Alba.—A hardy aquatic perennial, frequently found in our ponds. It flowers in June, and may be increased by dividing the roots. Height, 1 ft.

O

Odontoglossum Grande.—A most beautiful orchid, delighting in a temperature of from 60 to 70 degrees and an abundance of water during summer, but good drainage is essential. The blooms are yellow, spotted and streaked with venetian red, and are often 6 in. across. The pots should be two-thirds filled with crocks, then filled up with fibrous peat and sphagnum moss. During winter only a very little moisture should be given.

Oenothera.—The Evening Primroses are most useful and beautiful plants, well suited for ornamenting borders, beds, edgings, or rock-work. All the species are free-flowering, and grow well in any good, rich soil. The annual and biennial kinds are sown in the open in spring. The perennials may be increased by dividing the roots, by cuttings, or by seed, the plants from which will flower the first season if sown early in spring. They bloom in June and July. Height, 6 in. to 4 ft.

Olearia.—These evergreen shrubs thrive in peat and loam, and may be increased by division of the roots. O. Haastii has foliage resembling the Box, and a profusion of white, sweet-scented flowers in summer: a chalk soil suits it admirably. Height, 3 ft. to 4 ft.

Omphalodes Verna.—A hardy perennial which may be grown under the shade of trees in ordinary soil. It produces its flowers in March, and is increased by dividing the roots in autumn. Height, 6 in.

Oncidium Sarcodes.—Plant these Orchids firmly in well-drained pots, using equal parts of live sphagnum and fibrous peat. Give one good watering as soon as the potting is finished, and stand them in a light, warm part of the greenhouse. They will require very little more water until the roots have taken hold of the soil—only sufficient to keep the pseudo-bulbs from shrivelling—and during the winter months scarcely any moisture is needed. They flower in August. Height, 1-1/2 ft.

Onions.—Require a deep, rich, heavy soil. Where the ground is not suitable it should have had a good dressing of rotten manure the previous autumn, and left in ridges during the winter. Level the ground, and make it very firm just before the time of sowing. The seed should be sown early in March for the main crop and for salad and pickling Onions, and in August for summer use. Thin out to about 6 in. apart, excepting those intended to be gathered while small. The Tripoli varieties attain a large size if transplanted in the spring. The Silver-skins do best on a poor soil. For exhibition Onions sow in boxes early in February in a greenhouse; when about 1 in. high prick out, 3 in. apart, into other boxes; give gentle heat and plenty of air, and when they have grown 6 in. high put them in a cool frame until the middle of April, when they must be planted in the open, 1 ft. apart.

Ononis Rotundifolia (Round-leaved Restharrow).—A charming hardy evergreen of a shrubby nature. It will grow in any ordinary garden soil, and is increased by seed, sown as soon as it is ripe. It is most effective in clumps, and blooms from June to September. Height, 1-1/2 ft.

Onopordon.—Half-hardy perennials of a rather interesting nature and of easy cultivation. Sow the seed any time between March and June. They require the protection of a frame or greenhouse during winter, and produce flowers in July. Height, 6 in. to 8 ft.

Onosma Taurica (Golden Drop).—This hardy herbaceous plant is very pretty when in flower, and suitable for rock-work. It requires a well-drained vegetable mould, and to be planted where it can obtain plenty of sun. It is increased from cuttings taken in summer, placed in a cucumber frame, kept shaded for about a fortnight, and hardened off before the winter. The flowers succeed one another from June to November. Height, 1 ft.

Opuntia Rafinesquii (Hardy Prickly Fig).—A dwarf hardy Cactus with sulphur-coloured flowers, produced from June to August; very suitable for dry spots in rock-work. It grows best in peat with a little sand, and is propagated by separating the branches at a joint, and allowing them to dry for a day or so before putting them into the soil. Height, 2 ft.

Orange, Mexican.—See "Choisya."

Orchids.—The four classes into which these charming and interesting plants are divided may be described as (1) those coming from the tropics, (2) from South Africa, (3) from the South of Europe, and (4) our native varieties. The first require a stove, the second a greenhouse, the third and fourth slight protection during winter. As their natural character differs so widely it is necessary to ascertain from what part of the globe they come, and to place them in houses having as near as possible the same temperature and humidity as that to which they are accustomed. The pots in which they are grown should be filled with fibrous peat and sphagnum moss, largely mixed with charcoal, and abundant drainage ensured. They are propagated by dividing the root stocks, by separating the pseudo-bulbs, and, in case of the Dendrobiums, by cuttings. Orchis Foliosa (Leafy Orchis) may be grown in the open ground in good sandy loam. When once established it is best not to disturb it, but if needed it may be increased by division, after the tops have died down. Orchis Fusca (Brown Orchis) may likewise be planted in the open, in a sheltered position, in fine loam and leaf-mould, the soil to be well drained, yet constantly moist.

Origanum Pulchellum.—Popularly known as the Beautiful Marjoram, this plant is useful for cutting for vases. It is perennial and hardy, and thrives in a dry situation with a sunny aspect and in a sandy soil. The bloom is in its best condition in October. The rooted shoots may be divided in spring or almost at any other period, or it may be propagated by taking cuttings in summer. Height, 1-1/2 ft.

Ornithogalum.—O. Arabicum bears a large white flower with a shiny black centre. It is a fine plant for pot culture, or it may be grown in water like the Hyacinth. It may be planted in the open early in spring in sandy loam and peat. Take it up before the frost sets in and store it in a dry place, as it requires no moisture while in a dormant state. In September the flowers are produced. Height, 6 in. O. Umbellatum (Star of Bethlehem) is a pretty little flower often found in English meadows, is quite hardy, and once established may be left undisturbed for years. It throws up large heads of starry flowers, which are produced in great abundance. While in a dormant state the bulbs should be kept almost dry. It is propagated by off-sets; flowers in May. Height, 1 ft.

Orobus.—These hardy perennials bear elegant Pea-shaped blossoms. The plants will grow readily in any light soil, and are easily increased by root-division in the spring, or by seeds. They flower in June. Height, 2 ft. to 3 ft.

Osmanthus.—These elegant hardy evergreen shrubs succeed best in light, sandy loam, and like a dry situation. They may be increased by cuttings of the young shoots with a little old wood attached, or they may be grafted on to common Privet. The variegated varieties are very beautiful. They grow well on chalk soils. Height, 4 ft. to 6 ft.

Othera Japonica.—A newly introduced evergreen shrub very similar to the Holly. It is perfectly hardy and may be treated in the same manner as that plant.

Ourisia Coccinea.—A hardy herbaceous, surface-creeping perennial of singular beauty as regards both leaf and flower. The soil in which it is grown must be well drained, a peat one being preferable; and the position it occupies must be well shaded from the rays of the midday sun. It flowers from May onwards to September, the cut bloom being admirable for mixing with fern leaves. As soon as new life starts in spring the roots may be divided. Height, 9 in.

Oxalis.—A genus of very pretty bulbous plants that thrive well in a mixture of loam, peat, and sand, or will grow in any light soil. Most of the tender kinds may be reared in a frame if protected from frost in the winter. After they have done flowering they should be kept dry until they begin to grow afresh. They are increased by off-sets from the bulb. The hardy species should be planted in a shady border, where they will grow and flower freely. The seeds of these may be sown in the open in spring. Some of the varieties have fibrous roots: these will bear dividing. They are equally suitable for pots, borders, or rock-work. Height, 9 in. to 3 ft.

Ox-Tongue.—See "Bugloss."

Oxythopis Campestris.—A hardy perennial with lemon-yellow flowers in June and July. It will grow in any good garden soil, and is propagated by seed only, which should be sown where the plants are intended to be grown. Height, 6 in.

P

Pachysandra.—This early hardy perennial has ornamental foliage and blooms in April. It will succeed in almost any soil, and may be increased by suckers from the roots. Height, 1 ft.

Paeonies.—These beautiful flowering plants are mostly hardy enough to endure our winters. The herbaceous kinds are increased by dividing the plants at the roots, leaving a bud on each slip. The shrubby species are multiplied by cuttings taken in August or September, with a piece of the old wood attached, and planted in a sheltered situation. Tree Paeonies require protection in winter, and may be propagated by grafting on to the others, by suckers, or by layers. New varieties are raised from seed. A rich, loamy soil suits them best. Height, 2 ft.

Palms from Seed.—Soak the seed in tepid water for twenty-four hours, then put them singly 1 in. deep in 2-in. pots filled with equal parts of loam, leaf-mould, and sand. Cover the pots with glass and stand them in the warmest part of a hothouse. Shade from strong sunshine, and keep the soil just moist. Re-pot as soon as the roots have filled the old ones.

Pampas Grass.—See "Gynerium."

Pampas Lily of the Valley.—See "Withania."

Pancratium.—A handsome class of plants. Their habit of growth is somewhat like that of the Amaryllis. They are admirably adapted for growing in pots in the greenhouse. They may also be planted in the open ground under a south wall. The bulbs should be placed in a composition of three parts light, sandy loam and one of vegetable mould. They are increased by off-sets from the roots, or by seeds, by which the new varieties are obtained. Height, 1 ft. to 2 ft.

Pandanus Veitchi (Variegated Screw Pine).—For table decoration or vases this is a most useful plant. It requires a warm greenhouse where a temperature of 60 or 70 degrees can be kept up throughout the year, and grows well in equal parts of peat and loam with one-sixth part sand. During the autumn a little liquid manure is beneficial. In the winter months it should be watered carefully, but in the summer it is improved by syringing with warm water. It is propagated very easily by suckers taken off in spring or summer, placed in a temperature of 75 degrees.

Panicum.—Handsome ornamental grasses. They will grow in any soil or situation. P. Capillare is an annual, suitable for bouquets or edgings; it is increased by seed. P. Altissimum, an annual, and P. Sulcatum, a most elegant greenhouse plant, are fine for specimens. P. Plicatum is highly ornamental and hardy, but is best grown as a conservatory or window plant; it has a Palm-like appearance, and is of quick growth. Most of the plants flower in July. They may be propagated by seed or by division of the roots. Average height, 1-1/2 ft.

Pansies (Heartsease).—Grow well from seed sown in July or August on a raised bed of light earth. They may also be increased from cuttings taken in August, September, April, or May, selecting young side-shoots and planting them in light earth mixed with silver sand. The cuttings should be kept in a cool frame, moderately moist, and shaded from the hot sun. They can likewise be increased by layers, merely pegging them down and not slitting them on account of their tendency to damp off. They may also be increased by dividing the roots in April or May. They should be planted where they will get all the morning sun, yet be sheltered from mid-day rays; in an open and airy situation, yet protected from cutting winds. While the plants are blooming they should be supplied with liquid manure.

Papaver (Poppy).—These showy flowers are most at home in a rich, light soil. They are easily raised from seed sown where they are intended to bloom. The perennials may also be increased by dividing the roots. They flower at midsummer. Height varies from 1 ft. to 3 ft.

Pardanthus Chinensis.—See "Iris."

Parsley.—In order to grow Parsley to perfection it is necessary that the ground be well drained, as the roots and stems must be kept dry, and the soil should be rich and light. Three sowings may be made during the year: the first in spring for late summer and autumn use, the next in June for succession, and another in August or September for spring and early summer use. Thin out or transplant, to 6 in. apart. Parsley takes longer than most seeds to germinate; it must therefore be watched during dry weather and watered if necessary. Plants potted in September and placed in a cold frame, or protected in the open from rain and frost with a covering of mats supported by arches, will be valuable for winter use.

Parsnips.—These succeed best in a rich soil, but the application of fresh manure should be avoided, as it induces forked and ill-shaped roots. Let the ground be trenched two spits deep and left ridged up as long as possible. As early in March as the weather will permit level the surface and sow the seed in drills 15 in. apart, covering it with half an inch of fine soil. When the plants are 2 or 3 in. high, thin them out to 9 in. apart. They may be taken up in November and, after cutting off the tops, stored in a pit or cellar in damp sand, or they may be left in the ground till required for use.

Passion Flower.—Cuttings of the young shoots strike readily in sand under glass. The plant likes a good loamy soil mixed with peat. A sheltered position with a south or south-western aspect should be assigned those grown out of doors, and the root should be well protected in winter. The flowers are borne on seasoned growth of the current year: this fact must be considered when pruning the plants. During the hot months the roots require a copious supply of water, and the foliage should be syringed freely. Passiflora Caerulea is fine for outdoor culture, and Countess Guiglini makes a capital greenhouse plant.

Pavia Macrostachya.—This is a deciduous hardy shrub or tree which bears elegant racemes of white Chestnut-like flowers in July. Any soil suits it. It is propagated by layers or by grafting it on to the Horse-chestnut. Height, 10 ft.

Peaches.—These are best grown on a strong loam mixed with old mortar; though any soil that is well drained will produce good fruit. When possible, a south wall should be chosen; but they are not particular as to position, providing they are afforded shelter from cold winds. November and February are the most favourable months for planting. The roots should be carefully arranged at equal distances apart, 3 or 4 in. below the surface of soil, and then covered with fine mould. Avoid giving manure at all times, except when the trees are bearing fruit heavily. Train the shoots about 6 in. apart, removing all the wood-buds except one at the base of the shoot and one at the point. Keep the flowers dry and free from frost by means of an overhead shelter, to which tiffany or canvas can be attached, which should, however, only be used so long as the cold weather lasts. To ensure good fruit, thin the same out to 6 in. apart as soon as it attains the size of a small pea, and when the stoning period is passed remove every alternate one, so that they will be 1 ft. apart. After gathering the fruit, remove any exhausted and weak wood, leaving all that is of the thickness of a black-lead pencil. To keep the foliage clean, syringe once a day with water; this may be continued until the fruit is nearly ripe. The following may be recommended for outdoor cultivation:—Hale's Early, Dagmar, and Waterloo for fruiting in July or August; Crimson Galande, Dymond, and the well-known Bellegarde for succession in September; and Golden Eagle for a late sort. When planted in quantities, Peaches should stand 20 ft. apart.

When grown under glass a day temperature of 50 degrees, falling to 45 degrees at night, is sufficient to start with, gradually increasing it so that 65 degrees by day and 55 by night is reached at the period of blossoming. Syringe the leaves daily until the flowers are produced, then discontinue it, merely keeping the walls near the pipes and the paths damp. As soon as the fruit is set the syringing should recommence. Water of the same temperature as that of the house should in all cases be used. When the fruit begins to ripen, cease once more the syringing until it is gathered, then admit air freely, wash the trees daily, and apply liquid manure to the roots in sufficient quantities to keep the soil moist during the time the trees are at rest. Rivers's Early, Pitmaston Orange, Dagmar, and Royal George are all good under glass.

Pears.—Wherever Apples are a success Pears will grow. As a rule, they are best grown dwarf. On light soils they should be grafted on to Pear stocks, but on heavy soils they are best worked on the Quince. The fruiting of young trees may be accelerated by lifting them when about five years old, spreading out the roots 1 ft. below the surface of the soil, and mulching the ground. The mulching should be raked off in the spring, the ground lightly stirred with a fork and left to sweeten, and another mulching applied when the weather becomes hot and dry. In pruning, leave the leading branches untouched, but let all cross shoots be removed, and the young wood be cut away in sufficient quantity to produce a well-balanced tree, and so equalise the flow of sap. Some of the pruning may be done in summer, but directly the leaves fall is the time to perform the main work. A good syringing once a week with the garden hose will keep the trees vigorous and free from insects. Should scab make its appearance on the leaves, spray them occasionally with Bordeaux Mixture, using the minimum strength at first, and a stronger application afterwards if necessary. There are over 500 varieties of Pears, so it is no easy matter to give a selection to suit all tastes, but a few may be named as most likely to give satisfaction. Louise Bonne de Jersey succeeds in almost any soil and in any situation, is a great favourite, and ripens its fruit in October. Beurre Giffard makes a fine standard, and ripens in July. Beurre Hardy is delicious in October and November. Doyenne du Comice is one of the best-flavoured, and is very prolific. Beurre d'Amanlis ripens in August. Williams's Bon Chretien, Aston Town, Pitmaston Duchess, Clapp's Favourite, Comte de Lamy, and Josephine de Malines are all reliable for dessert, while for stewing purposes Catillac, Black Pear of Worcester, Verulam, and Vicar of Winkfield are among the best. In orchards standards should be from 20 to 25 ft. apart; dwarfs 12 ft. to 1 rod.

Peas.—For the production of heavy summer and autumn crops a rich and deeply-stirred soil is essential, one of the best fertilisers being well-decayed farmyard manure; but for the earliest crop a poorer soil, if deep and well pulverised, will give the best results. Peas under 3 ft. in height do not require sticking, but they can be more easily gathered if a few small twigs are used to keep the haulm off the ground. If sown in successive lines the space between the rows should correspond with the height of the variety grown. A good plan is to arrange the rows 10 or 15 ft. apart, and crop the intervening spaces with early dwarf vegetables. The earliest varieties may be sown from November to February, on the warmest and most sheltered border: these may be gathered in May and June. The second early round, varieties, if sown from January to April, will be ready for gathering in June and July. The main crop round varieties may be sown from February to May: these will be ready to gather in July and August. The early wrinkled varieties may be sown from March to June, for gathering between June and September. Sow main crop and late varieties at intervals of fourteen days from March to May: these will be ready to gather in July, August, and September. When the plants are a couple of inches high draw the earth neatly round them, and stake the taller varieties as soon as the tendrils appear. Keep them well watered in dry weather, and if on a light soil a mulching of manure will be beneficial. As soon as the pods are setting apply weak liquid manure to the roots when the ground is moist.

Peas, Everlasting (Lathyrus Latifolia).—These well-known and favourite hardy perennials are very useful for covering trellises, etc. They will grow in any garden soil, and may be raised from seed sown early in spring in slight heat. Where there is no greenhouse or frame the seed may be planted, about 1/2 in. deep, round the edges of pots filled with nice, light soil, and covered with a sheet of glass, keeping the soil moist till the seed germinates. When the plants are strong enough they may be placed in their permanent quarters. They bloom from June to September. Old roots may be divided. Height, 6 ft.

Peas, Sweet.—These most beautiful and profuse blooming hardy annuals will grow almost anywhere, but they prefer a dry soil that is both rich and light. The seed should be sown as early in March as practicable, and in April and May for succession. When the plants are 2 or 3 in. high a few twigs may be placed among them, to which they will cling. The flowers are produced in July, and the more liberally they are gathered the longer the plants will continue to bloom. Height, 3 ft.

Pelargonium.—The shrubby kinds will grow well in any rich soil; loam and decayed leaves form a good compost for them. They require good drainage and plenty of air and light while in a vigorous state. Cuttings root readily in either soil or sand, especially if placed under glass. Most of the hard-wooded varieties are more easily increased by cuttings from the roots. The tuberous-rooted ones should be kept quite dry while dormant, and may be increased by small off-sets from the roots.

Pentstemon.—This charming hardy perennial is deserving of a place in every garden. It may be grown in any good soil, but a mixture of loam and peat is most suitable. The seed may be sown in April, and the plants transferred when strong enough to their flowering quarters; or it may be sown in a sheltered position during August or September to stand the winter. It may also be increased by dividing the roots in spring, as soon as growth begins. Cuttings of the young side-shoots about 6 in. long may be taken at any period—the middle of September is a good time; these should be placed under a hand-glass in sandy loam and leaf-mould. These cuttings will flower the first year. It blooms from May to October. Height, 2 ft.

Peppermint.—This may be grown on any damp or marshy soil, and increased by dividing the roots.

Perennials.—These are plants that die down during the winter, but spring up and produce new stems annually. Some, as for instance Antirrhinums and Pansies, flower the first season, but usually they do not bloom till the second season. Many of the species improve by age, forming large clumps or bushes. The stock is increased by division of the roots, which, if judiciously done, improves the plant. Like annuals, they are divided into classes of Hardy, Half-hardy, and Tender plants.

Hardy perennials do not require artificial heat to germinate the seeds, or at any period of their growth, but are the most easily cultivated of all plants. Seed may be sown from March to midsummer, transplanting in the autumn to their flowering quarters; or it may be sown in August and September in a sheltered position to stand the winter.

Half-hardy plants require artificial heat to germinate their seed, and must be gradually introduced into the open. They may be sown during March and April in frames or a greenhouse, when many will bloom the first season. If sown between May and the end of August they will flower the following spring and summer. They require protection during winter, such as is afforded by a cold pit, frame, or greenhouse, or the covering of a mat or litter. Tender perennials may be sown as directed above, but the plants should be kept constantly under glass.

Some perennials, such as Pinks, Carnations, Saxifrages, etc., do not die down, but retain their leaves. These are called evergreen perennials.

Pergularia.—Very fragrant twining plants, suitable for trellis-work, arbours, etc. A rich soil suits them best. They are easily increased by cuttings sown in sand under glass. They flower at midsummer. Height, 8 ft. to 12 ft.

Perilla Nankinensis.—A plant of little merit, except for its foliage, which is of a rich bronze purple. It bears a cream-coloured flower in July. It may be raised in the same manner as other half-hardy annuals, and prefers a light, loamy soil. Height, 1 1/2 ft.

Periploca Graeca.—A hardy, deciduous, twining shrub, which will grow in any soil, and may be increased by layers or by cuttings placed under glass. It flowers in July. Height, 10 ft.

Periwinkle.—See "Vinca."

Pernettya.—An American evergreen shrub, which, like all of its class, thrives best in sandy peat; it delights in partial shade, and a moist but well-drained position. It is increased by layers in September, which should not be disturbed for a year. It is a good plan to mulch the roots with leaf-mould or well-rotted manure. Height, 5 ft.

Petunias.—These ornamental half-hardy perennials prefer a mixture of sandy loam and vegetable mould, but will grow in any rich, light soil. Seeds sown in March or April, at a temperature of from 65 to 75 degrees, make fine bedding plants for a summer or autumn display. As the seeds are very minute, they should be covered merely with a dusting of the finest of soil. Moisture is best supplied by standing the pots up to the rims in water. Pot off singly, harden off, and plant out at the end of May. May also easily be raised from cuttings, which will strike at any season in heat, but care must be taken that they do not damp off. They flower in July and August. Height, 1-1/2 ft. to 2 ft.

Phacelia Campanularia.—A superb, rich blue, hardy annual. It will grow in any soil, and is easily raised from seed sown in spring. Flowers are borne in June. Height, 1-1/2 ft.

Phalaris.—P. Arundinacea is the well-known perennial Ribbon Grass; it is easily grown from seed, and the root allows division. P. Canariensis is the useful canary seed: it may be propagated from seed on any soil. Height, 1-1/2 ft.

Philadelphus.—Among the best of our flowering shrubs, producing a wealth of sweetly-scented flowers. For cultivation, see "Syringa."

Philesia.—An American evergreen shrub which grows best in peat, but will thrive in any light soil. It should occupy a cool position, but be well sheltered from winds. It is increased by suckers. Flowers in June. Height, 4 ft.

Phillyrea.—This effective border evergreen will grow in any ordinary garden soil, and may be increased either by layers or cuttings. It has dark green shining leaves, and is quite hardy. Height, 6 ft.

Phlomis (Lion's Tail).—This effective hardy perennial will grow in any rich, light soil in a warm position, and is a fine lawn plant. Flowers are produced from June to August. It may be increased by seed or division. Protect the plant from damp in winter. Height, 3 ft.

Phlox.—For richness of colour and duration of bloom there are few plants that can rival either the annual or perennial Phlox. The trailing kinds are very suitable for small pots or rock-work, C. Drummondi for beds, and the French perennials, P. Decussata, for mixed borders. A rich, loamy soil suits them best, and they must never lack moisture. They are easily raised in spring from seed, and the perennials may be increased by cuttings placed under glass, or by division. Flower in July. Height, 1 ft. to 2 ft.

Phormium Tenax.—A greenhouse herbaceous plant which succeeds best in rich loam. It flowers in August, and may be propagated by dividing the roots. Height, 3 ft.

Phygelius Capensis.—A greenhouse perennial bearing carmine and yellow flowers in June, but is hardy enough to be grown on a warm border. It is increased by off-sets from the root, taken off in May. Height, 2 ft.

Physalis (Winter Cherry).—A rich, light soil is most suitable for the stove and greenhouse kinds, cuttings of which root freely under glass. The hardy kinds will grow in any soil, and are increased by seed. P. Francheti produces seed-pods over 2 in. in diameter, the Cherry-like fruit of which is edible and makes a fine preserve. It is larger than that of the old Winter Cherry, P. Alkekengi. They flower in August. Height, 1 ft. to 2 ft.

Physianthus Albens.—This evergreen climber is a good plant for training to the rafters of a greenhouse. It grows well in a mixture of sandy loam and peat, and should receive bold treatment. Its white flowers are produced in July. The plant is propagated by seeds, also by cuttings. Height, 20 ft.

Physostegia.—Ornamental hardy herbaceous plants, ranging in colour from white to purple. They like a rich soil, and can be raised from seed sown in March. They also bear division. July and August are their flowering months. Height, from 1 ft. to 5 ft.

Phyteuma Hallierii.—A very pretty hardy perennial. It will thrive in any soil, blooms from May to August, and can be readily increased by seed or division. Height, 1-1/2 ft.

Phytolacca Decandra (Virginian Poke).—A very fine herbaceous plant, bearing bunches of pretty black berries. It requires a rich soil and plenty of room for its widespreading branches. Cuttings will strike under glass, or the seed may be sown in autumn. It flowers in August. Height, 6 ft.

Picotees.—See "Carnations."

Pimelias.—Very beautiful, compact, and free-growing greenhouse everlasting shrubs. The most suitable soil consists of three parts sandy peat and one part loam, with good drainage. June or July is their flowering season. They may be grown from seed or young cuttings 2 in. long, placed in sandy peat, with a little bottom heat. Do not give too much water. Height, 2 ft. to 4 ft.

Pimpernel.—See "Anagallis."

Pinguicula Grandiflora (Great Irish Butterwort).—This handsome, hardy bog-plant produces deep violet-blue flowers in August and September. It may be grown in any damp soil and increased by division. Height, 1-1/2 ft.

Pinks.—Will live in almost any soil, but if large blooms are required rich earth is essential. They are increased by pipings taken in May or June. These should be planted out in October, but must be given a well-drained position, as too much wet is injurious to them. Do not set the roots too deep, but let the collar of the plant be on a level with the soil.

Pinus.—As a tall specimen tree nothing is more graceful than the Corsican Pine (Pinus Laricio). P. Strobus Nana is a curious dwarf variety, rarely exceeding 3 ft. in height. The Argentea Aurea is also of dwarf habit. Its leaves, which are green in summer, change to a bright golden colour in winter. The Umbrella Pine (Sciadopitys) is a very striking conifer, and does well everywhere. It gets its name from its leaves being set at regular intervals round the branches, like the ribs of an umbrella. The Pinus may be increased by layers, or by sowing the cones in spring, after they have opened out, in rather sandy soil, covering them lightly.

Piping.—This consists in drawing out the young grass, or shoots, from the joints of Pinks, etc., from May to July being the time for doing so. Place them in light, sandy soil, and cover them with a hand-glass. Towards the end of September they may be planted out in beds or potted off in rich, light loam. In either case they must not be planted too deeply. The crust of the soil should be level with the collar of the plant. If the pots are put into a frame the plants will require very little water during winter, but as much air should be given as is possible. In March re-pot them, using 8-1/2-in. pots.

Platycodon (Japanese Balloon Flower).—Hardy and elegant herbaceous plants, requiring a sandy soil. They may be raised either from seeds or from cuttings of the young growth; they flower in July. Height, 1 ft.

Platystemon Californicus.—Pretty hardy annuals which thrive in a sandy soil. They are easily raised from seed sown in March or April, and bring forth their flowers in August. Height, 1 ft.

Pleroma Elegans.—A beautiful evergreen shrub for a greenhouse. Pot in equal parts of loam, peat, and sand. It flowers in July. Cuttings may be struck in peat in a rather warm temperature. Height, 4 ft.

Plumbago.—These pretty evergreens will grow in any soil, and can be propagated in September by cuttings of half-ripened wood having a heal, planted in a sandy soil, and kept near the glass in a greenhouse. They flower in June. Height, 3 ft. P. Occidentalis is a charming greenhouse climber. P. Capensis Alba is a greenhouse evergreen shrub, flowering in November, and growing to a height of 2 ft. P. Larpentae is good for a sunny border, in light soil: it bears terminal clusters of rich violet-purple flowers in September. Height, 1 ft. Plumbagoes require very little attention in winter.

Plums.—Almost any soil will grow this useful fruit. Young trees may be planted at any time, when the ground is friable, from November to March, but the earlier it is done the better. The situation should be somewhat sheltered. In exposed positions protection may be afforded by a row of damson trees. Many varieties are suitable for growing on walls or sheds, where they are trained into fans, as cordons, and other decorative designs; but it must not be overlooked that until the trees are well established a great deal of fruit is necessarily lost by the severe pruning and disbudding which is required to bring the tree into shape. A pyramid-shaped tree is useful, and is easily grown by training one straight, central shoot, which must be stopped occasionally so that fresh side branches may be thrown out, which of course must be kept at the desired length. A bush tree about 7 ft. in height is undoubtedly the best form of growth, and needs but a minimum amount of attention. In pruning wall trees the main object is to get the side-shoots equally balanced, and to prevent the growth advancing in the centre. The bush form merely require the removal of any dead wood and of cross-growing branches. This should be done late in the summer or in the autumn. The trees are frequently attacked by a small moth, known as the Plum Fortrix, which eats its way into the fruit and causes it to fall. In this case the fallen unripe fruit should be gathered up and burned, and the trees washed in winter with caustic potash and soda. For growing on walls the following kinds may be recommended: Diamond, White Magnum Bonum, Pond's Seedling, and Belle de Louvain for cooking; and Kirke, Coe's Golden Drop, and Jefferson for dessert. For pyramids and bushes, Victoria, Early Prolific, Prince Engelbert, Sultan, and Belgian Purple are good sorts. In orchards Plums should stand 20 ft. apart.

Poa Trivalis.—A very pretty, dwarf-growing, variegated grass. Plant in a moist situation in a rich, light, loamy soil. It is increased either by seed or division.

Podocarpus.—See "Cephalotaxus."

Podolepis.—Hardy annuals bearing yellow and red and white flowers. A mixture of loam and peat is most suitable for their growth. They are easily raised from seed sown in March, and bloom from June to August. Height, 1-1/2 ft.

Podophyllum Peltatum (Duck's Foot, or May Apple).—Grown chiefly for its foliage and berries, this hardy herbaceous perennial forms a pleasing spectacle when planted in moist soil under trees; it likewise makes a splendid pot-plant. A mixture of peat and chopped sphagnum is what it likes. The pots are usually plunged in wet sand or ashes on a northern border. It is propagated by cutting the roots into pieces several inches in length, with a good bud or crown on each. During May and June the plant produces small white Dog-rose-like flowers. Height, 1 ft.

Poinsettia Pulcherrima.—A stove evergreen shrub which produces lovely crimson bracts in the winter. Plant in sandy loam, give plenty of water to the roots, and syringe the leaves frequently. In early spring cut down the branches to within three or four eyes of the old wood. These cuttings, if laid aside for a day to dry and then planted under glass, will form new plants. It flowers in April. Height, 2 ft.

Polemonium (Jacob's Ladder).—Hardy perennial border plants of an ornamental character and of the easiest culture. Any soil suits them, and they merely require sowing in the open either in spring or autumn. P. Richardsoni is most commonly met with, its blue flowers being produced in early autumn. Height, 1-1/2 ft.

Polyanthus.—Sow the seed late in autumn in well-drained boxes of light, rich mould; cover it very lightly, place under glass, and water sparingly, but give enough to keep the plants moist. The seed requires no artificial heat to germinate it. The roots should be divided each year as soon as they have flowered, and fresh soil given. The single varieties only are florists' flowers. The Polyanthus is a species of primrose, grows best in a rather shady position in a loam and peat compost, and produces its flowers in May. Height, 6 in.

Polygala Chamaesbuxus.—A hardy evergreen trailing plant requiring a peat soil in which to grow. It may be increased from seed or by division of the roots. May is the time at which it blooms. Height, 6 in.

Polygala Dalmaisiana.—This showy evergreen shrub needs a greenhouse treatment. Soil—three parts peat, one part turfy loam, and a little sand. It flowers in March. To increase it, top the shoots, which will cause it to throw out new ones. Take the new growth off when it is 3 in. long, and place it under glass in a propagating house. Height, 1 ft.

The hardy annual varieties of Polygala are obtained by seed sown in peat. These flower at midsummer. (See also "Solomon's Seal.")

Polygonatum.—These pretty herbaceous plants are quite hardy. The flowers, which are borne in May or June, are mostly white. Plants succeed best in a rich soil. They may be raised from seed, or the roots can be divided. Height, 1ft. to 3 ft.

Polygonum Brunonis (Knotweed).—This strong-growing creeping perennial plant is not particular as to soil so long as it can enjoy plenty of sunshine. The shoots root of themselves and must be kept in check, else they will choke other things. It flowers in August, after which the leaves assume beautiful autumnal tints. Height, 1 ft.

Pomegranate.—This requires a deep, loamy soil and a warm, airy situation. May be propagated by cuttings of the shrubs or the root, putting the cuttings into light, rich soil, or by layers. The double kinds of Punica, or Pomegranate, should be grafted on to the single ones. There is a dwarf kind, bearing scarlet flowers in August, which requires heat.

Poppies.—See "Papaver" and "Stylophorum."

Portulaca.—The seeds of the hardy annual species of this genus may be sown in a sheltered open spot in spring. The half-hardy annuals should be sown thinly in boxes during March and placed in gentle heat. Harden off and plant out in May, as soon as the weather permits, in a light, dry soil where it can get a good amount of sunshine. Its brilliant and striking colour admirably adapts it for small beds, edgings, or rock-work; and it will succeed in dry, hot sandy positions where scarcely any other plant would live. It flowers in June. Height, 6 in.

Potatoes.—Ground intended for Potatoes should be dug deeply in the autumn, thoroughly drained, well manured and trenched, and left rough on the surface during the winter. At the beginning of February stand the tubers on end in shallow boxes, and expose them to the light to induce the growth of short, hard, purple sprouts. Allow one sprout to each tuber or set, rubbing off the rest. They may be planted at any time from the end of February to the end of March in rows 1-1/2 to 2-1/2 ft. asunder, placing the sets 6 in. deep and from 6 to 9 in. apart. As soon as growth appears keep the ground well stirred with the hoe to prevent the growth of weeds, and when the tops are 4 to 6 in. high ridge the earth up about them. Directly flower appears, pick it off, as it retards the growth of the tubers. They should be taken up and stored in October. If short of storage room dig up every other row only, and give the remaining ridges an additional covering of earth. They keep well this way.

Potentilla.—Handsome herbaceous plants with Strawberry-like foliage. They will grow in any common soil, and may be increased by dividing the roots or by seeds treated like other hardy perennials. The shrubby kinds are well adapted for the fronts of shrubberies, and are propagated by cuttings taken in autumn and planted in a sheltered situation. They flower at midsummer. Height, 1-1/2 ft.

Potting.—Great attention must be paid to this important gardening operation. It is necessary that the pots used be perfectly clean, and, if new, soaked in water for several hours previously, otherwise they would absorb the moisture from the soil to the detriment of the roots. At the bottom of the pots place a few layers of crocks, and on these some rough mould so as to ensure perfect drainage. For all delicate, hard-wooded plants one-third of each pot should be occupied with drainage, but a depth of 1-1/2 in. is sufficient for others. Lift the plant carefully so as not to break the ball of earth round the roots, and fill in with mould round the sides. In order to supply water readily the pots must not be filled up to the rim. Pot firmly, and in the case of hard-wooded plants ram the earth down with a blunt-pointed stick; soft-wooded ones may be left rather looser. Give shade till the plants have recovered themselves. The soil used for potting should be moist, but not clammy. A rather light, rich loam is most suitable for strong-growing plants; peat for slow-growing, hard-wooded ones, like Ericas, Camellias, etc.; and a mixture of light loam, one-third its bulk of leaf-soil, and silver sand in sufficient quantity to make the whole porous for quick-growing, soft-wooded plants, such as Pelargoniums, Calceolarias, Fuchsias etc.

Pratia Repens (Lobelia Pratiana).—This pretty little creeping perennial is very suitable for the front of rock-work. It requires a well-drained vegetable soil and all the sun it can get. It is self-propagating. Though pretty hardy, it is safer to pot it off in autumn and place it in a cold frame throughout the winter. Flowers are produced in June, and are succeeded till cut off by frost.

Primroses.—See "Primulas," and "Streptocarpus."

Primulas.—This genus embraces the Auricula, the Polyanthus, and the Primrose. The greenhouse varieties are among the most useful of our winter-flowering plants. The seed may be sown at any time from March to July in a pot of two-year-old manure, leaf-mould, or fine, rich mould, but not covering it with the soil. Tie a sheet of paper over the pot and plunge it in a hotbed. Sufficient moisture will be communicated to the seed by keeping the paper damp. When the plants make their appearance remove the paper and place the pot in the shady part of the greenhouse. When they are strong enough to handle, pot off into 4-1/2 in. pots, and stand them near the glass. The roots may be divided as soon as the plants have done flowering. The hardy kinds may be sown in the open. It should be borne in mind that the seed must be new, as it soon loses its germinating properties. These flower in March or April. Height, 6 in.

Prince's Feather.—An ornamental hardy annual, producing tall spikes of dark crimson flowers and purple-tinted foliage. It is not particular as to soil, and merely requires sowing in the open in spring to produce flowers in July. Height, 2 ft.

Privet.—See "Ligustrum."

Prophet's Flower.—See "Arnebia."

Prunella Grandiflora.—A pretty hardy perennial, suitable for a front border or rock-work, bearing dense spikes of flowers from May to August. It grows well in any ordinary soil, and is propagated by division. Height, 6 in.

Pruning.—The main objects to bear in mind in Pruning any kind of bush or tree are to prevent a congested growth of the branches, to remove any shoots that cross each other, as well as all useless and dead wood, and to obtain a well-balanced head. It may be done either in August or in the winter when the sap is at rest, after the worst of the frosts are over, the end of February being usually suitable; but the former period is generally acknowledged to be the better, especially for fruit-trees. The cuts should be clean and level, and when a saw is used should be made smooth with a chisel and covered with grafting wax. In all cases as little wound as possible should be presented. Root-pruning has for its object the suppression of over-vigorous growth and the restoration of old trees to a bearing condition. It consists in taking off all the small fibres, shortening the long roots to within 6 or 8 in. of the stem, and cutting away any bruised or injured roots before the trees are first planted out. The mode of procedure in the case of old or unproductive trees is to open the earth in autumn 3 ft. from the stem of the tree, and to saw through two-thirds of the strongest roots. The opening is then filled in with fresh mould. Should the growth still be too vigorous, the soil must be opened again the following season and the remaining roots cut through, care being taken not to injure the young fibrous roots.

Prunus.—Beautiful early-flowering trees, which will grow in any soil, and can be increased by seeds or suckers.

Ptelia Trifoliata (Hop Tree).—This is very suitable for planting on the borders of still waters, where its long frond-like leaves, which turn to a golden yellow in autumn, produce a fine effect. It blooms in June, and is propagated by layers. Height, 10 ft.

Pulmonarias (Lungworts).—Hardy perennials that require but little attention; may be grown in any common soil, and propagated by division at any time. They flower in April and May. Height, 1 ft.

Pumilum.—See "Heleniums."

Pumpkins.—Valuable for soups and pies in winter, and in summer the young shoots are an excellent substitute for Asparagus. For their cultivation, see "Gourds."

Punica Granata Nana.—A greenhouse deciduous shrub which flowers in August. The soil in which it is placed should be a light, rich loam. It can be most freely multiplied by layers, and cuttings will strike in sand under glass. Height, 4 ft.

Puschkinia (Striped Squills).—This charming bulbous plant may be grown in any light, rich mould, provided it is drained well. The bulbs may be separated when the clumps get overcrowded, late in summer, after the tops have died down, being the most suitable time to do so. If planted in a warm position it will begin to flower in March, and continue in bloom till May. Height, 8 in.

Pyrethrum.—The greenhouse kinds grow in any rich soil, and young cuttings planted under glass root readily. The hardy kinds are not particular as to soil so long as it is not cold and wet, and are increased by seeds sown in heat in February if wanted for early use, or in the open during March and April for later growth. The crowns may be divided either in autumn or spring: each eye or bud will make a fresh plant. Young plants produced in this way in the autumn require the protection of a frame during the winter. They flower in July. Height varies from 6 in. to 3 ft.

Pyrola.—A handsome hardy plant, suitable for a moist, shady situation. It is raised from seed, or will bear dividing, but is rather hard to grow. Height, 6 in.

Pyrus Japonica.—See "Cydonia."

Q

Quaking Grass.—See "Briza."

Quercus Ilex.—A handsome evergreen Oak, delighting in a deep, loamy soil. It is propagated by seed sown as soon as it is ripe.

Quinces.—Plant in autumn in a moist but well-drained soil. Cuttings of stout stems 6 or 8 in. long, firmly and deeply planted in a shady situation, mulched with leaf-mould, and kept watered in dry weather, will take root; but the surest method of propagation is by layers, pegged down in the soil and detached the following year. A good watering with liquid manure will swell the fruit to a large size. Keep the branches well thinned out and cut them regular, so as to let in light and air and form nicely shaped trees. The pruning should be done as soon as the leaves fall. In orchards they should stand 1 rod apart.

R

Radish.—For an early supply sow on a gentle hotbed under a frame in January, February, and March. For succession sow thinly on a warm and sheltered border early in March. Follow on with sowings in the open till the middle of September. The Black Spanish and China Rose should be sown during August and September for winter use. Lift in November, and store in sand in a cool place. Radishes should be liberally watered in dry weather, and the soil made rich and light some time before sowing commences.

Ragged Robin.—See "Lychnis."

Ragwort.—See "Jacobaea."

Ramondia Pyrenaica.—A pretty dwarf perennial, suitable for moist interstices of rock-work. It should be planted in a slanting position, so that the roots, while absorbing plenty of moisture, will not rot through being continually in stagnant water. Peat soil suits it best. It may be increased by division in spring. If grown from seed it takes two years before flowers are produced. During the height of summer it is in full beauty.

Rampion.—The roots are used in cooking, and also for salads. For winter use sow in April in rows 12 in. apart, covering the seeds lightly with fine mould, and thin out to 4 in. apart. Sow at intervals for a succession.

Ranunculus.—These prefer a good stiff, rather moist, but well-drained loam, enriched with well-rotted cow-dung, and a sunny situation. February is probably the best time for planting, though some prefer to do it in October. Press the tubers (claws downwards) firmly into the soil, placing them 2 or 3 in. deep and 4 or 5 in. apart. Cover them with sand, and then with mould. Water freely in dry weather. Protect during winter with a covering of dry litter, which should be removed in spring before the foliage appears. They flower in May or June. Seeds, selected from the best semi-double varieties, sown early in October and kept growing during the winter, will flower the next season. They may likewise be increased by off-sets and by dividing the root. The claws may be lifted at the end of June and stored in dry sand. The plants are poisonous. Height, 8 in. to 12 in.

Raphiolepis Ovata.—Beautiful evergreen shrubs, producing long spikes of white flowers in June. A compost of loam, peat, and sand is their delight. Cuttings will strike in sand under glass. Height, 4 ft.

Raspberries.—A rich, moist, loamy soil is most suitable for their cultivation. Suckers are drawn by the hand from the old roots any time between October and February, and set in groups of three in rows 6 ft. apart. If taken in October, the young plants may be pruned early in November. It is usual to cut one cane to the length of 3 ft., the second one to 2 ft., and the third to within a few inches of the ground. As soon as the year's crop is gathered, the old bearing shoots are cut clean away, the young canes are drawn closer together, and at the end of August the tops of the tall ones are pinched off. When the leaves have fallen all the suckers are drawn out and the canes pruned (about four being left to each root). The canes are then tied and manure applied. About May they are, if necessary, thinned out again, and the suckers that are exhausting both soil and plant removed. They produce their fruit on one-year-old canes, which wood is of no further use. The general way of training them is by tying the tops together, or by training them in the shape of a fan on a south wall, but perhaps the best way is to tic them about equal distances apart round hoops supported by light sticks. Seed may be separated from the fruit, dried, and sown early in February on a gentle hotbed. Prick off into good rich mould, harden off by the middle of May, and plant in rich soil. Train them and keep down suckers. When they are grown tall pinch off the tops. Red Antwerp, Yellow Antwerp, Prince of Wales, Northumberland Filbasket, Carter's Prolific, and White Magnum Bonum are all good sorts.

Red-hot Poker.—See "Tritoma."

Red Scale.—See "Scale."

Red Spiders.—These troublesome pests which appear in the heat of summer, may be got rid of by constantly syringing the plants attacked, and by occasionally washing the walls, etc., with lime or sulphur.

Retinospora Filifera.—A large-growing, hardy evergreen shrub. It may be grown in any light soil, and increased by seed, or by cuttings planted under glass in the shade. It flowers in May.

Rhamnus (Buckthorn).—Fine evergreen shrubs, of hardy habit and quick growth. They may be grown in any soil, but prefer a sheltered situation, and are very suitable for planting near the sea. R. Latifolius has handsome broad leaves. Some, such as R. Alaternus and R. Catharticus, attain large proportions, the former reaching 30 ft. and the latter 10 ft. in height. They may be propagated by layers or by seed.

Rheum Palmatum.—This species of rhubarb makes an effective plant for the back portion of a border. It does well in rich loam, flowering in June, and is increased by dividing the root. Height, 5 ft.

Rhodanthe (Swan River Everlasting).—These beautiful everlasting flowers are half-hardy annuals and are suitable for beds or ribbons, and make most graceful plants for pot culture, placing four plants in a 5-in. pot. They thrive best in fibrous peat or a rich, light soil, and prefer a warm situation. Used largely for winter bouquets, and are perfect gems for pot culture. A succession of bloom may be obtained by sowings made in August, October, and March. The temperature of the seed-pots should be kept at from 60 to 70 degrees, and the soil kept constantly damp with water of the same heat. After potting the seedlings remove them to a cooler house and keep them near the glass. Those sown in March may be planted in the open in June, where they will flower in autumn. Height, 1 ft.

Rhodochiton—This evergreen climber makes a fine plant for trellis-work. It is more suitable for the greenhouse, though it may be grown in the open in summer. A light, rich, well-drained soil is its delight, and it may be propagated by seed or by cuttings under glass. In the greenhouse it should not be placed near the pipes. July is its time for flowering. Height, 10 ft.

Rhododendrons.—Plant in October in peat, or in a compost of sandy, turfy loam, with a good proportion of decayed leaves and charred refuse. The best position for them is a sheltered one where they can get a moderate amount of sunshine to develop the flower-buds. They like plenty of moisture, but the ground must be well drained. If it is desired to shift their position spring is the best time, the next best being October. They are propagated by layers or seeds, and the small wooded kinds by slips torn off close to the stems, planted in sand, and placed under glass in heat. The seed should be sown early in spring in pans of peat soil, and covered very lightly. Place the pans in a frame, and when the soil becomes dry stand the pans in water nearly up to the rims until the surface is moist. Pot off when strong enough to handle, and keep close in the frame till fresh roots are produced, then harden off. Rhododendrons may, when desired, be transplanted in spring, even after the flower-buds are well advanced, if care be taken not to break the ball of earth round their roots. They bloom at the end of May. Height, 4 ft.

Rhubarb.—Seed may be sown thinly during April in drills 1 ft. apart. Thin out the plants 12 in. from each other, and let them grow on till the following April, then plant them out 4 ft. apart in deeply trenched ground into which a good quantity of well-rotted manure has been worked. Large roots may be divided in autumn or early spring; every portion of the root that has a crown will make a fresh plant. When the last of the crop has been pulled, fork in a dressing of old manure. It may be forced out of doors by covering the ground thickly with stable manure, and placing large flower-pots over the plants to bleach them; but if forced in a frame the light need not be excluded. None but the earliest kinds should be selected for forcing.

Rhubarb, Chilian.—See "Gunnera."

Rhus (Sumach).—Lovely shrubs, growing in any ordinary soil. The young shoots of R. Cotinus are clothed with round leaves which change to bright crimson and orange, surmounted with fluffy pink seed-vessels, while R. Glabra Laciniata resembles a tree fern. They may be propagated either by layers or cuttings. Height, 8 ft. to 10 ft.

Rhynchospermum (Trachelospermum) Jasminoides.—A pretty, evergreen, woody climber for the conservatory, which succeeds best in a compost of light loam and peat; is of easy culture, and readily increased by cuttings. It is a fine plant for rafters or trellis, and produces in July deliciously fragrant white flowers at the ends of the branches. Height, 10 ft.

Ribes (Flowering Currants).—Well-known shrubs, growing in any soil, and flowering early in spring. The colours vary from crimson to white. They may be raised from cuttings either in autumn or early spring. Height, 4 ft.

Richardia Aethiopica.—A fine herbaceous perennial with very bold leaves. It needs a good supply of water, and on dry soils should be planted in trenches. A light, rich mould is best for it, and it should have sufficient sun to ripen the wood. Lift it in September and winter in the greenhouse. It is increased from off-sets from the root, and flowers in March. Height, 2 ft.

Ricinus, or Palma Christi (Castor-oil Plant, etc.).—The foliage of these half-hardy annuals is very ornamental. The plants like a rich soil. Sow the seed early in spring in a slight heat, harden off gradually, and put out at the end of May in a warm, sheltered spot. They may also be propagated by cuttings. Height, 3 ft. to 6 ft.

Robinia.—All these shrubs have fine, Fern-like foliage which changes colour in autumn. The Pea-shaped flowers vary in colour from cream to purple, and while in bloom the plants are very handsome. They grow in any soil, flower in May and onwards, and are increased by layers. Height varies, the Rose Acacia (Hispida) reaching 10 ft., while the Locust Tree (Pseudo-Acacia) grows to the height of 40 ft.

Rock Cress.—See "Arabis."

Rocket (Hesperis).—The hardy perennials like a light, rich soil, and need to be frequently divided. The best time to divide them is just after they have done flowering, when they should be potted off, planting them out again in the spring. The annual and biennial kinds merely require to be sown in the open border. Most of the Rockets give forth greater fragrance towards evening. Their flowering season is June. Height, 1 ft. to 1-1/2 ft.

Rock Rose.—See "Cistus" and "Helianthemum."

Rodgersia Podophylla.—A hardy perennial having immense bronze foliage. It thrives best in a moist, peaty soil; flowers from May to July, and may readily be increased either by seed or division. Height, 3 ft.

Rogiera Gratissima.—A pretty evergreen stove shrub, which is often trained to a single stem so as to form a standard. It succeeds in sandy loam and peat. It may be sunk in the flower-border during the height of summer, but must be taken indoors before frost sets in. Cuttings placed in sand under a hand-glass in heat will strike. It flowers in June. Height, 3 ft.

Romneyi Coulteri.—This grand white-flowered Poppy Tree is quite hardy, and will grow in any light, rich soil. It blooms in August and September, and may be increased by seed or by division. Height, 4 ft.

Rose Campion.—A pretty hardy perennial which may be grown from seed sown in autumn, choosing a sheltered site, or in March in a frame or under a hand-glass, transplanting it in the autumn into a light, rich, loamy soil. Height, 2 ft.

Rosemary (Rosmarinus Officinalis).—This hardy evergreen shrub should occupy a dry and sheltered position. Its fragrant purple flowers are produced in February. Cuttings of the ripened wood, if planted in spring, will strike root freely. Height, 2 ft.

Roses.—A good, deep, loamy soil, well drained, but which retains a certain amount of moisture, is the most suitable. The position should be sheltered, yet open and exposed to the sun. The latter part of October or November is the most favourable time for planting, but it may be continued with safety until the commencement of March. A fortnight before planting the holes should be dug out 1-1/2 or 2 ft. deep, and plenty of old manure thrown in and trodden down. On this a good layer of fine mould should be placed, so that the roots do not come in contact with the manure. Great care must be taken not to expose the roots to the cold air. When the ground is quite ready for their reception dip the roots in a pail of water, then spread them out carefully on top of the mould, fill in the earth, and tread it firmly. If the plants are standards they require to be firmly staked. Precaution is necessary not to plant too deeply, keeping them as near as possible at the depth at which they were previously grown, in no case exceeding 1 in. above the mark which the earth has left on the stem. Three weeks after planting tread the earth again round the roots. Pruning should be done in March, except in the case of those planted in spring, when the beginning of April will be early enough. Cut away all of the wood that is unripe, or exhausted and dead. Dwarf growers should be cut back to within two or three buds of the previous year's growth, but five or six eyes may be left on those of stronger growth. The majority of climbing and pillar roses do not require to be cut back, it being only necessary to take out the useless wood. In pruning standards aim at producing an equally balanced head, which object is furthered by cutting to buds pointing outwards. At the first sign of frost the delicate Tea and Noisette Roses need to be protected. In the case of standards a covering of bracken fern or straw must be tied round the heads; dwarfs should have the soil drawn up over the crowns, or they may be loosely covered by straw. Apply a top-dressing of farm-yard manure to the beds before the frosts set in, as this will both nourish and protect the roots. Fork it in carefully in the spring. Cow manure is especially valuable for Tea Roses. After the first year of planting most of the artificial manures may, if preferred, be used; but nothing is better than farmyard stuff. If the summer be dry, water freely in the evening. Roses may be propagated by cuttings in the summer or autumn. The slips should be 5 or 6 in. long, of the spring's growth, taken with 1 in. of the previous year's wood attached. A little bottom-heat is beneficial. They may also be increased by grafting or by separating the suckers. Keep a sharp look-out for maggots in the spring, which will generally be found where the leaves are curled up. These must be destroyed by hand-picking. Green fly can be eradicated with tobacco wash. Mildew may be cured by sprinkling the leaves with sulphur while dew is on them.

Rose of Heaven.—See "Viscaria Coeli Rosa."

Rose of Sharon.—See "Hibiscus Syriacus."

Rubus.—See "Blackberries."

Rudbeckia (Cone Flower.)—Hardy annuals yielding yellow flowers in July. They are readily grown from seed sown early in spring, and will grow in any garden soil, but naturally succeed best in deeply-worked, well-manured ground. They may be increased by division in October or November, as well as in spring-time. Height, 3 ft.

Ruscus Aculeatus (Butchers Broom).—A hardy evergreen shrub which thrives in any rich soil, and may be increased by division of the root. Height, 1 ft.

Ruta Graveolens.—This hardy evergreen shrub is a species of Rue. It enjoys a good, rich soil, in which it flowers freely in August. Cuttings may be struck under a hand-glass. Height, 3 ft.

Ruta Patavina (Rue of Padua).—For rock-work this hardy perennial is very useful. It likes a dry yet rich and light soil. At midsummer it produces an abundance of greenish-yellow flowers. It can be raised from seed, or cuttings may be struck under a hand-glass. Height, 6 in.

S

Saffron, Spring.—See "Bulbocodium."

Sage.—This useful herb likes a rich, light soil, and is propagated by division of the root, by cuttings, or by seed.

Saintpaulia Ionantha.—The leaves of this plant spread themselves laterally just over the soil, forming a rosette, in the centre of which spring up large violet-like flowers. It is a continuous bloomer. A rather light, rich soil or vegetable mould suits it best. The seed, which is very minute, should be sown early in spring, in gentle heat: to prevent it being washed away, the pots may stand up to the rims in water for a while when the ground wants moisture. Height, 1 ft.

St. John's Wort.—See "Hypericum."

Salix Reticulata.—A dwarf creeping plant whose dark green leaves eminently fit it for the rock-work or carpet bedding. It will grow in any soil, but prefers a moist one, and produces unattractive brown flowers in September. Propagated in spring by detaching rooted portions from the parent plant and planting them in moist, sandy loam. Height, 2 in.

Salpiglossis.—Very beautiful half-hardy annuals which are greatly prized for cut bloom. A light but not over-rich soil suits them best. The seed may be sown in the open border early in spring, or preferably on a hotbed at the same period. For early flowering raise the plants in the autumn, and winter them in a frame or greenhouse. Flowers are produced in July and August. Height, 2 ft.

Salsafy (Vegetable Oyster).—Sow the seed in any good garden soil—deep sandy loam is best—towards the end of April in drills 1 ft. apart, and thin the plants out to a distance of 6 in. from each other. The roots may remain in the ground till required for use, or be lifted in October and stored in the same way as Beet or Carrots. They are prepared for table in the same manner as Parsnips, and are also used for flavouring soups.

Salvia.—Very showy flowers, well worth cultivating, and easily grown in a rich, light soil. The annuals and biennials may be sown in the open early in spring. The herbaceous kinds are increased by dividing the roots; the shrubby varieties by cuttings of the young wood planted under glass in March; while the stove species require to be placed in heat. They flower in August in the open. Heights vary, according to the kinds, but S. Coccinea and S. Patens, which are most commonly met with in gardens, grow to a height of 2 ft.

Sambucus (The Elder).—Useful deciduous shrubs. S. Nigra Aurea has golden foliage, and is suitable for town gardens. The silvery variegated variety (Variegata), is fine for contrasting with others. They may all be propagated by cuttings or by division. Flower in June.

Sand Wort.—See "Arenaria."

Sanguinaria Canadensis (Bloodroot).—A hardy perennial, curious both in leaf and flower. It requires a light, sandy soil, shade, and moisture; is propagated by seed sown in July, also by division of the tuberous roots, and it blooms in March. The tubers should be planted 5 in. deep and 3 in. apart. Height, 6 in.

Santolina.—This hardy evergreen shrub grows freely in any soil. It flowers in July, and is increased by cuttings. Height, 2 ft.

Sanvitalia.—Interesting, hardy annual trailers, which may be readily raised from seed sown in March or April, and merely require ordinary treatment. They produce their golden and brown and yellow flowers in July. Height, 1 ft.

Saponaria.—These grow best in a mixture of sandy loam and peat or decayed vegetable soil. The annuals may be sown either in autumn, and wintered in a frame, or in the open in April. The perennials are increased by seed or by division of the root, and young cuttings of the branching species root freely if planted under glass. S. Ocymoides, on account of its trailing nature, and S. Calabrica make fine rock-work plants. The leaves of S. Officinalis, or Soap Plant, if stirred in water form a lather strong enough to remove grease spots. They bloom in June and July. Height, 6 in. to 2 ft.

Sarracenia.—Curious herbaceous plants, requiring to be grown in pots of rough peat, filled up with sphagnum moss, in a moderately cool house having a moist atmosphere. They flower in June, and are increased by division. Height, from 9 in. to 1 ft.

Sauromatum Guttatum.—This makes a good window or cool greenhouse plant. Pot the tuber in good loam and leaf-soil, and keep the mould only just damp until the foliage, which follows the flowers, appears. When the foliage fails, keep the tubers dry till spring. If grown out of doors the tubers must be lifted before frost sets in.

Savoys.—Sow the seed in March or April, and when the plants are 2 in. high remove them to a nursery-bed, selecting the strongest first. Let them remain till they are about 6 in. high, then transplant them, 18 in. apart, in well-manured soil. Their flavour is greatly improved if they are frozen before being cut for use.

Saxifrage.—These beautiful Alpine perennials delight in a light, sandy soil, and are easily propagated by seed or division. It is most convenient to grow the rare and tender kinds in pots, as they require the protection of a frame in winter. Saxifraga Sibthorpii is very suitable for the lower and damper parts of rock-work; it is hardy, and sheds its seed freely. S. Umbrosa (London Pride) makes a neat border, and is also useful for rock-work. S. Sarmentosa (Mother-of-Thousands) is a fine hanging plant for greenhouse or window. They flower in April. Height, mostly 4 in. to 6 in., but some grow as high as 1-1/2 ft.

Scabious.—Ornamental and floriferous hardy biennials, which grow freely in common soil. The seed may be sown at any time between March and midsummer; transplant in the autumn. They bloom in June. Height, 1 ft to 3 ft. (See also "Cephalaria.")

Scale.—Red Scale may be easily overcome with a strong solution of soft soap applied with a sponge. White Scale is harder to deal with. Syringe frequently with strong soapsuds heated to 120 degrees. If the plant is badly attacked it is best to destroy it.

Schizanthus.—Extremely beautiful and showy annuals. A rather poor, light soil is most suitable for their growth. For early flowering sow the seed in autumn, and keep the young plants in a frame or greenhouse throughout the winter. For a succession of bloom sow in the open border early in the spring. They flower in July and August. Height, 2 ft.

Schizopetalum.—This singular and delightfully fragrant annual does best in a mixture of loam, peat, and sand, or sandy loam and leaf-mould. Sow the seed in pots in the spring, place in a greenhouse, and when large enough to handle, plant out in the open border, or it may be kept in an airy part of the house, where it will bloom in June. Height, 1 ft.

Schizostylis Coccinea (Crimson Flag, or Kaffre Lily).—A most lovely autumn-blooming plant, producing abundant spikes of Izia-like flowers about 2 ft. high. It is suitable for pot-culture or planting outdoors, and is quite hardy. It requires a rich, light soil.

Scillas (Squills).—Very useful spring-flowering bulbs. They are hardy, and do well in any position in light soil. When mixed with Crocuses and Snowdrops they produce a very charming effect. To get perfection of bloom they require deep planting. S. Siberica especially looks well when grown in pots with Snowdrops. Scilla roots are poisonous. General height, 1 ft.

Scorzonera.—Sow in March in light soil in rows 18 in. apart. Thin the plants out to about 7 in. one from the other. They may perhaps be ready for use in August, but to have large roots they should be left till they are two years old. They may remain in the ground till wanted for use, or they may be lifted in October and stored like Beet, etc. This vegetable is scraped and thrown into cold water for a few hours, then boiled in the same way as Carrots and Parsnips.

Scutellaria.—These plants will grow in any good soil. The hardy perennials flower in July. The greenhouse varieties merely require protecting in the winter. They all bear division of the root, and are easily raised from seed. Height, 1-1/2 ft.

Scyphanthus.—An elegant and curious trailer, which is best grown in a loamy soil. It may be increased from seed sown in April, and it flowers in August. Height, 2 ft.

Sea Cabbage.—See "Crambe Cordifolia."

Seakale.—The readiest way of propagating this useful vegetable is by off-sets, but it may be raised from seed sown in March or April in rows 1 ft. apart. Thin out the young plants to 6 in. in the rows, and transplant in February or March into well-trenched, deep, rich soil in rows 2 ft. apart and the plants 15 in. asunder. Keep the plants to one crown, or shoot, and remove all flower-shoots as they appear. In dry weather give a liberal quantity of liquid manure. Cropping may commence after the roots have been planted two years.

Sea Lavender.—See "Statice."

Sea Milkweed.—See "Glaux."

Sedum (Stonecrop).—This well-known hardy perennial is suitable for pots or rock-work. It delights in a light, sandy soil, and is readily increased by division or cuttings. It flowers in June or July. Height, 3 in.

Seed-Sowing.—Two of the most important points in the sowing of seed are the proper condition of the ground and the regular and uniform depth at which the seed is sown. Seeds require light, heat, air, and moisture for their germination. The ground should be light, and in such a condition that the young roots can easily penetrate it, and in all cases should be freshly dug so as to communicate air and moisture: it should be neither too wet nor too dry. The most favourable time for seed-sowing is just before a gentle rain. If sown too early on cold, wet ground, the seed is apt to rot; when sown too shallow in a dry time, there may not be sufficient moisture to cause it to sprout. The seed should be sown evenly. The size of a seed is a nearly safe guide as to the depth at which it should be sown. For instance, Beans and Peas of all kinds should be sown about a couple of inches deep, while very small flower-seeds merely require to be just covered. As to the time for sowing, see "Annuals," "Biennials," and "Perennials."

Seeds, the Protection of.—In order to protect seeds against birds, insects, and rodents, soak them in water containing 20 or 25 per cent, of mineral oil. Vegetable seeds, such as Haricot Beans and Peas, should be soaked for twelve hours, and the pips of Apples and Pears for double that time. For soaking the finer seeds, bitter liquids, such as that of Quassia and Gentian, should be used.

Sempervivum (Houseleek).—The hardy kinds are well known, and may often be seen growing on the roofs of cottages and on walls. They make good rock-work plants, and are easily increased by off-sets. The more tender kinds are suitable for the greenhouse. These should be planted in sandy loam and old brick rubbish. They require but very little water; more may be given when they are in flower. Cuttings, after being laid aside for a day or two to dry, will soon make root. Height, 6 in.

Senecio Pulcher (Noble Crimson Groundsel).—A warm position and a deep, rich, well-drained soil are needed for this flower. It may be propagated by cutting the roots into pieces 5 or 6 in. long, and dibbling them into light soil. It is also increased by the rootlets, which send up small growths in spring. Protect from damp and frost, and keep a sharp look-out for slugs. The flowers are produced in autumn. Height, 3 ft.

Senna, Bladder.—See "Colutea."

Sensitive Plant.—See "Mimosa."

Shallots.—Plant the bulbs in November, or in February or March, in rows 9 in. apart, and the bulbs 6 in. one from the other. In July, when the tops are dying down, lift the bulbs, lay them in the sunshine to dry, then store them in a cool place.

Shamrock.—See "Trifolium Repens."

Sheep Scabious.—See "Jasione."

Shortia Galacifolia.—A hardy, creeping Alpine evergreen, having oval leaves, slightly notched at the margins, which turn to a brilliant crimson during the autumn and winter months. In April and May it produces pearly-white flowers, somewhat Campanulate in form. It may be planted in early autumn or spring. A light, rich soil suits it best, and it delights in partial shade. It is a lovely plant for rock-work. Height, 6 in.

Shrubs.—Deciduous shrubs may be transplanted at any time during late autumn or winter when the ground is not too wet. Evergreen shrubs may be moved either early in autumn or in April or May, damp, warm, but not sunny weather being most suitable for the operation. They rejoice in a clean, healthy soil, such as good loam; animal manure does not agree with them, but wood ashes, or charcoal powder with a little guano, may be used. Cuttings of shrubs or trees may be taken in September, placed in a mixture of sandy loam and leaf-mould with 1/2 in. of sand on top, and covered with a hand-glass; 5 to 8 in. is a good length for the cuttings, all of which, with the exception of about 1 in., should be buried, and preferably with a heel of old wood. Keep the soil just damp and give shade.

Shrubs for Lawns.—Monkey Puzzle (Araucaria Imbricata)—mix wood ashes and burnt refuse with the soil; Thujopsis Delabrata, Thujopsis Borealis (of taller growth), Irish Yews, Cupressus Lawsoniana Erecta Viridis, Thujas Orientalis, Vervaeneana, Semperaurescens, Standard Rhododendrons, Standard and Pyramid Hollies, Yucca Gloriosa (a perfect picture), Yucca Recurva (the best hardy plant for vases). The Cercis tree is also well adapted for lawns.

Sicyos.—This hardy annual somewhat resembles the Cucumber, but is scarcely worth growing except as a curiosity. The seeds are sown on a hotbed in spring, potted off when strong enough, and transferred to the open border early in June. It is a climber, and flowers in August. Height, 3 ft.

Sidalcea.—Very pretty hardy perennials, of easy culture. S. Candida has pure white flowers closely arranged on the upper part of the stems. S. Malvaeflora bears beautifully fringed, satiny pink flowers. They will grow in any good soil from seed sown in autumn and protected during the winter, or they may be increased by division of the roots. Height, 3 ft.

Silene (Catchfly).—Elegant plants, delighting in a light, rich soil. Sow the seeds of the annual varieties early in April where they are intended to bloom. Silene Pendula, when sown in the autumn, makes a pleasing show of pink flowers in the spring. The roots of the herbaceous kinds may be divided in spring. The shrubby sorts are increased by cuttings planted under a hand-glass. The dwarfs make fine rock-work ornaments. Flowers are produced in June and July. Height, 2 in. to 1-1/2 ft.

Silphium Aurantiacum.—A good and hardy border perennial, which produces during July and August large deep orange-yellow flowers resembling a Sunflower. It is very useful for cutting, will grow anywhere, and can be increased by dividing the root. Height, 4 ft.

Sisyrinchium Grandifolium(Satin Flower, or Rush Lily).—A light loam suits this plant, which is moderately hardy. The soil should be moist, but not wet. It does not like being disturbed, but when necessary the crowns may be divided in autumn, taking care to spread the roots well out. It blooms in April or May. Height, 1 ft.

Skimmia.—Neat-growing, dwarf evergreen shrubs having Laurel-like leaves, and producing a profusion of scarlet berries in winter. They succeed in any ordinary soil, but thrive best in peat and loam; and are propagated by cuttings placed in heat under glass.
