Part 28

Leucojum (Snowflake).--Also known as St. Agnes' Flower. Handsome plants. The flowers are pure white, every petal being tipped with green, dropping in a cluster of from six to eight blooms, each nearly 1 in. long. They grow freely in almost any soil, sandy loam being preferable. Increased by off-sets from the bulb, or by seed as soon as it is ripe. The spring snowflake blooms in March, the summer variety in June. The latter is a much more vigorous plant than the former. Height, 12 in. to 18 in.

Leucophyton Browni.--A popular white-foliaged bedding plant, which may be increased by dibbling cuttings in sandy soil and placing them in a cool frame.

Lewisia Rediviva.--This makes a pretty rock-plant. It is a perennial and quite hardy, but requires plenty of sun. During April and May it produces large flowers varying in colour from satiny rose to white. The most suitable soil is a light loam mixed with brick rubbish. It is increased by division of the root, or it may be raised from seed. Height, 3 in.

Leycesteria Formosa.--Ornamental plants, the flowers resembling Hops of a purple colour. They will grow in any soil, but need protection in winter. They are multiplied by cuttings. Height, 3 ft.

Liatris Pycnostachya.--A curious old herbaceous perennial, now seldom met with, sending up late in summer a dense cylindrical purple spike 2 ft. high. It needs a rich, light, sandy soil, and to be protected during the winter with a thick covering of litter. The roots may be divided in the spring. Height, 3 ft.

Libertia Formosa.--The narrow foliage and spikes of pure white flowers, produced in May and June, render this hardy perennial very ornamental. The soil should consist of equal parts of loam and peat. It is propagated by dividing the roots. Height, 1 ft.

Libonia Floribunda.--This is a winter-flowering plant, and is easily grown in a cool greenhouse. It is very useful for table decoration, its slender red and yellow tubes of bloom being very effective, but it does not do to keep it for any length of time in a room where there is gas. When flowering has ceased, encourage new growth by giving it plenty of water, air, and sunlight. The new shoots should be cut back in May, and the tips of them used as cuttings, which strike readily in good mould. Height, 2 ft.

Ligustrum (Privet).--L. Ovalifolium is a handsome hardy evergreen, of very rapid growth, and one of the best ornamental hedge plants in cultivation, especially for towns or smoky situations. L. Japonicum is likewise ornamental and hardy: Tricolor is considered one of the best light-coloured variegated plants grown. L. Coriaceum is a slow-growing, compact bush with very dark, shining green leaves, which are round, thick, and leathery. Privet will grow in any soil or situation, and is readily increased by cuttings planted in the shade in spring.

Lilac--See "Syringa."

Lilium.--The Lily is admirably adapted for pot culture, the conservatory, and the flower border, and will flourish in any light soil or situation. To produce fine specimens in pots they should be grown in a mixture of light turfy loam and leaf-mould. Six bulbs planted in a 12-in. pot form a good group. The pots should have free ventilation, and the bulbs be covered with 1 in. of mould. For outdoor cultivation plant the bulbs 4 to 5 in. deep, from October to March. After once planting they require but little care, and should not be disturbed oftener than once in three years, as established plants bloom more freely than if taken up annually. Give a thin covering of manure during the winter. Lilium seed may be sown in well-drained pots or shallow boxes filled with equal parts of peat, leaf-mould, loam, and sand. Cover the seeds slightly with fine mould and place the boxes or pots in a temperature of 55 or 65 degrees. A cold frame will answer the purpose, but the seeds will take longer to germinate. The Lancifolium and Auratum varieties have a delicious fragrance.

Lilium--continued.

CANDIDUM (the Madonna, or White Garden Lily) should be planted before the middle of October, if possible, in groups of three, in well-drained, highly-manured loam. Should they decline, take them up in September and re-plant at once in fresh, rich soil, as they will not stand being kept out of the ground long. They are increased by off-sets. As soon as these are taken from the parent bulb, plant them in a nursery-bed; after two years they may be transferred to the garden. This Lily is quite hardy, and needs no protection during winter.

LANCIFOLIUM make very fine pot-plants, or they may be placed in a sunny situation in the border, but in the latter case they must have a thick covering of dry ashes in winter. If grown in pots place them, early in March, in rich, sandy soil. Three bulbs are sufficient for an 11-in. pot. Give very little water, but plenty air in mild weather. Let them grow slowly. When all frost is over place pans under them, mulch the surface with old manure, and supply freely with air and water. They are propagated by off-sets.

MARTAGON (or Turk's Cap) requires the same treatment as the Candidum, with the exception that a little sand should be added to the soil.

TIGRINUM (Tiger Lily) also receives the same treatment as the Madonna. When the flower-stems grow up they throw out roots. A few lumps of horse manure should be placed round for these roots to lay hold of. They are increased by the tiny bulbs which form at the axis of the leaves of the flower-stem. When these fall with a touch they are planted in rich, light earth, about 6 in. apart. In four or five years' time they will make fine bulbs.

AURATUM and SZOVITZIANUM (or Colchicum) thrive best in a deep, friable, loamy soil, which should be well stirred before planting. If the soil is of a clayey nature it should be loosened to a depth of several feet, and fresh loam, coarse sand, and good peat or leaf-mould added, to make it sufficiently light.

For PARDALINUM (the Panther Lily) and SUPERBUM mix the garden soil with three parts peat and one part sand, and keep the ground moist. They should occupy a rather shady position.

All the other varieties will succeed in any good garden soil enriched with leaf-mould or well-decayed manure.

Lily of the Valley.--Set the roots in bunches 1 ft. apart, and before severe weather sets in cover them with a dressing of well-rotted manure. They should not be disturbed, even by digging among the roots. If grown in pots, they should be kept in a cool place and perfectly dry when their season is over: by watering they will soon come into foliage and flower again. For forcing put ten or twelve "buds" in a 5-in. pot--any light soil will do--plunge the pot in a sheltered part of the garden. From this they may be removed to the forcing-house as required to be brought into bloom. Plunge the pots in cocoa-nut fibre and maintain an even temperature of from 65 to 70 degrees.

Limnanthes Douglasii.--Very elegant and beautiful hardy annuals, which are slightly fragrant. They must be grown in a moist and shady situation. The seeds ripen freely, and should be sown in autumn to produce bloom in June, or they may be sown in spring for flowering at a later period. Height, 1 ft.

Linaria.--These all do best in a light, sandy loam, and make good plants for rock-work. L. Bipartita is suitable for an autumn sowing. The other annuals are raised in spring. L. Triornithophora is a biennial, and may be sown any time between April and June, or in August. The hardy perennial, L. Alpina, should be sown in April, and if necessary transplanted in the autumn. Linarias flower from July to September. Height, 6 in. to 1 ft.

Linnaea Borealis.--A rare, native, evergreen creeping perennial. From July to September it bears pale pink flowers; it makes a pretty pot-plant, and also does well in the open when planted in a shady position. It enjoys a peat soil, and is propagated by separating the creeping stems after they are rooted. Height, 11/2 in.

Linum (Flax).--This succeeds best in rich, light mould. The Linum Flavum, or Golden Flax, is very suitable for pot culture; it grows 9 in. in height, and bears brilliant yellow flowers. It requires the same treatment as other half-hardy perennials. The Scarlet Flax is an annual, very free-flowering, and unsurpassed for brilliancy; easily raised from seed sown in spring. Height, 11/2 ft. The hardy, shrubby kinds may be increased by cuttings placed under glass. A mixture of loam and peat makes a fine soil for the greenhouse and frame varieties. They flower from March to July.
