Part 3

Amaryllis.--These plants bear large drooping bell-shaped lily-like blossoms. They thrive best in a compost of turfy loam and peat, with a fair quantity of sand. The pots must in all cases be well drained. Most of the stove and greenhouse species should be turned out of their pots in autumn, and laid by in a dry place until spring, when they should be re-potted and kept liberally supplied with water. A. Reticulata and A. Striatifolia bloom best, however, when undisturbed. Discontinue watering when the foliage shows signs of failing, but avoid shrivelling the leaves. The hardy varieties should be planted 6 in. deep in light, well--drained soil, and allowed to remain undisturbed for two or three years, when they will probably require thinning out. They are increased by off-sets from the bulbs.

The Belladonna (Belladonna Lily) should be planted in June in a sheltered border in rich, well-drained soil.

Formosissima (the Scarlet Jacobean Lily) is a gem for the greenhouse, and very suitable for forcing, as it will bloom two or three times in a season. It should be potted in February.

Lutea (Sternbergia) flowers in autumn. Plant 4 in. deep from October to December.

Purpurea (Vallota Purpurea or Scarborough Lily) is a very beautiful free bloomer. October and November or March and April are the most favourable times for potting, but established plants should be re-potted in June or July.

Ambrosia Mexicana.--A hardy annual of the simplest culture. Sow the seed in spring in any fine garden soil. Height, 1-1/2 ft.

American Plants.--These thrive most in a peat or bog soil, but where this cannot be obtained a good fertile loam, with a dressing of fresh cow manure once in two years, may be used; or leaf-mould and soil from the surface of pasture land, in the proportions of three parts of the former to one of the latter. The soil should be chopped up and used in a rough condition. Sickly plants with yellowish foliage may be restored by applying liquid manure once a week during the month of July. A light top-dressing of cow manure applied annually, and keeping the roots free from stagnant water, will preserve the plants in good health.

Ammobium.--Pretty hardy perennials which may be very easily raised from seed on a sandy soil. Flower in June. Height, 2 ft.

Ampelopsis.--Handsome and rapid climbers, with noble foliage, some changing to a deep crimson in autumn. The Veitchii clings to the wall without nailing, and produces a profusion of lovely leaves which change colour. Any of the varieties may be grown in common garden soil, and may be increased by layers.

Anagallis (Pimpernel.)--Very pretty. Sow the hardy annuals in the open early in March; the biennials or half-hardy perennials in pots in a greenhouse or a frame, and plant out when strong enough. May also be increased by cuttings planted in ordinary soil under glass. Flower in July. Height, 6 in.

Anchusa.--Anchusa Capensis is best raised in a frame and treated as a greenhouse plant, though in reality it is a hardy perennial. The annual and biennial kinds succeed well if sown in the open in rich soil. All are ornamental and open their flowers in June. Height, 1-1/2 ft. (See also "Bugloss.")

Andromeda.--An ornamental evergreen shrub, commonly known as the Marsh Cystus, and thriving in a peat soil with partial shade. May be grown from seed sown directly it is ripe and only lightly covered with soil, as the seed rots if too much mould is placed over it. Place the seedlings in a cold frame and let them have plenty of air. It is more generally increased by layers in September, which must not be disturbed for a year. Drought will kill it, so the roots must never be allowed to get dry. It flowers in April and May. Height, 2 ft.

Androsace.--Pretty little plants, mostly hardy, but some require the protection of a frame. They grow best in small pots in a mixture of turfy loam and peat. Water them very cautiously. They flower at different seasons, some blooming as early as April, while others do not put forth flower till August. They can be increased by division as well as by seed. Height, 6 in.

Anemones.--These are highly ornamental, producing a brilliant display of flowers. The scarlets make very effective beds. They are mostly hardy, and may be grown in any moist, light, rich garden soil, preferably mixed with a good proportion of silver sand. They should occupy a sunny and well-drained situation. For early spring flowering plant from October to December, placing the tubers 2-1/2 or 3 in. deep and 4 or 5 in. apart, with a trowelful of manure under each plant, but not touching them. A little sea sand or salt mixed with the soil is a preventive of mildew. If planted in February and March they will bloom from April to June. They are increased by seeds, divisions, or off-sets; the greenhouse varieties from cuttings in light loam under glass. The tubers will not keep long out of the ground. In growing from seed choose seeds from single-flowering plants; sow in March where they are intended to flower 1 in. deep and 9 in. apart; cover with leaf-mould. Two or three sowings may be made also during the summer. Height, 6 in. to 2 ft.

Anemonopsis Macrophylla.--A rather scarce but remarkably handsome perennial, producing lilac-purple flowers with yellow stamens in July and August. It will grow in ordinary soil, and may be increased by division. Height, 2 ft.

Angelonia Grandiflora Alba.--An elegant and graceful greenhouse plant, giving forth a delicious aromatic odour. It grows best in a compost of turfy loam and peat, but thrives in any light, rich soil. Take cuttings during summer, place them under glass, but give a little air occasionally. Height, 1-1/2 ft.

Annuals.--Plants of this description arrive at maturity, bloom, produce seed, and die in one season.

Hardy.--The seed should be sown thinly in the open borders during March, April, or May in fine soil, covering slightly with well-prepared mould--very small seeds require merely a dusting over them. When the plants are large enough to handle, thin them out boldly, to allow them to develop their true character. By this means strong and sturdy plants are produced and their flowering properties are enhanced. Many of the hardy annuals may be sown in August and September for spring flowering, and require little or no protection from frost.

Half-Hardy.--These are best sown in boxes 2 or 3 in. deep during February and March, and placed on a slight hotbed, or in a greenhouse at a temperature of about 60 degrees. The box should be nearly filled with equal parts of good garden soil and coarse silver sand, thoroughly mixed, and have holes at the bottom for drainage. Scatter the seeds thinly and evenly over the soil and cover very lightly. Very small seeds, such as lobelia and musk, should not be covered by earth, but a sheet of glass over the box is beneficial, as it keeps the moisture from evaporating too quickly. Should watering become necessary, care must be taken that the seeds are not washed out. As soon as the young plants appear, remove the glass and place them near the light, where gentle ventilation can be given them to prevent long and straggly growth. Harden off gradually, but do not plant out until the weather is favourable. Seed may also be sown in a cold frame in April, or in the open border during May; or the plants may be raised in the windows of the sitting-room.

Tender.--These must be sown on a hotbed, or in rather stronger heat than is necessary for half-hardy descriptions. As soon as they are large enough to be shifted, prick them off into small pots, gradually potting them on into larger sizes until the flowering size is reached.

Anomatheca Cruenta.--This produces an abundance of bright red flowers with a dark blotch and a low growth of grass-like foliage. It is suitable for either vases, edges, or groups. Plant the bulbs in autumn in a mixture of loam and peat, and the plants will flower in July. They require a slight protection from frost. If the seed is set as soon as it is ripe it produces bulbs which will flower the following year. Height, 6 in.

Antennaria.--Hardy perennial plants, requiring a rich, light soil. They flower in June and July, and may be increased by cuttings or division. The heights of the various kinds range from 3 in. to 2 ft.

Anthemis Tinctoria (Yellow Marguerites).--These perennials are almost hardy, needing protection merely in severe weather. They are readily raised from seed sown in gentle heat early in spring or by slips during the summer months. Transplant into light soil. As pot plants they are very effective. June is their flowering period. Height, 1-1/2 ft.

Anthericum Liliago (St. Bernard's Lily).--One of the finest of hardy plants, and easy to grow. Planted in deep, free, sandy soil, it will grow vigorously, and in early summer throw up spikes of snowy-white, lily-like blossoms from 2 to 3 feet in height. It may be divided every three or four years, but should not be disturbed oftener. Mulching in early springtime is advantageous.

Anthericum Liliastrum (St. Bruno's Lily).--This hardy perennial is a profuse bloomer, throwing up spikes of starry white flowers from May to July. Treat in the same manner as the foregoing. Height, 2 ft.

Anthoxanthum Gracila.--Sweet vernal grass. It is graceful and ornamental, and is used for edgings. Sow in spring, keeping the seed moist until it germinates. Height, 6 in.

Anthyllis Montana.--A fine hardy perennial for rock-work. It is of a procumbent habit, and has a woody nature. A vegetable soil is best suited for its growth, and its roots should be in contact with large stones. It may be increased by cuttings taken in spring and planted in the shade in leaf-mould. It flowers at midsummer. Height, 6 in.

Antirrhinum (Snapdragon).--Handsome hardy perennials; most effective in beds or borders. They stand remarkably well both drought and excessive rainfall, and succeed in any common soil. Seeds sown early in spring produce flowers the same year. For spring bedding, sow in July; keep the young plants in a cold frame, and plant out in March or April. Choice sorts may be plentifully increased by cuttings taken in July or August. Flower from July to September. Height, 1-1/2 ft. to 2 ft.
