Astragalus Lotoides.—This pretty little trailer is of the same height as A. Hypoglottis, and merely requires the same treatment. It flowers in August.
Astrantia.—This herbaceous plant is quite hardy, and will thrive in any good garden soil, producing its flowers in June and July. Seed may be sown either in autumn or spring. Height, 1-1/2 ft. to 2 ft.
Atragene Austriaca.—Handsome, hardy climbers, which may be grown in any garden soil. They flower in August, and are increased by layers or by cuttings under glass. Height, 8 ft.
Atriplex.—Straggling hardy annuals of very little beauty. Will grow in any soil if sown in spring, and only require ordinary attention. Flower in July. Height, 5 ft.
Aubergine.—See "Egg-Plant."
Aubrietia.—An early spring-blooming hardy perennial. Very ornamental either in the garden or on rock-work, the flowers lasting a long time. An open and dry situation suits it best. May be readily raised from seed, and increased by dividing the roots or by cuttings under a glass. Flowers in March and April. Height 6 in.
Aucuba.—Hardy evergreen shrubs, some having blotched leaves. They look well standing alone on grass plots, and are indifferent to soil or position. Cuttings may be struck in any garden soil under a hand-glass in August, or by layers in April or May. When the male and female varieties are planted together, the latter produce an abundance of large red berries, rendering the plant very showy and ornamental. They bloom in June. Height, 6 ft.
Auricula.—This is a species of primrose, and is sometimes called Bear's Ear from the shape of its leaves. It succeeds best in a mixture of loam and peat, or in four parts rotten loam, two parts rotten cow dung, and one part silver sand; delights in shade, and will not bear too much water. It makes an effective border to beds, and is readily propagated by off-sets taken early in autumn, or in February or March, by division of roots immediately after flowering, or from seed sown in March on gentle heat in firmly pressed light, rich soil, covered with a piece of glass and shaded from the sun till the plants are well up, when sun and air is needed. When large enough to handle, prick them out in a cold frame 6 in. apart, and keep them there through the winter. Take care to press the soil well round the roots of off-sets. October is a good time for making new borders. The half-hardy kinds require the protection of a house in winter. Height, 6 in.
Avena Sterilis.—A very singular hardy-annual ornamental grass, generally known as Animated Oats. Very useful in a green state for mixing with cut flowers. Sow in March or early in April. Height, 3 ft.
Azaleas (Greenhouse).—A good soil for these deciduous shrubs is made by mixing a fair quantity of silver sand with good fibrous peat. The plants must never be allowed to become too wet nor too dry, and must be shaded from excessive sunshine. After they have flowered remove the remains of the blooms, place the plants out of doors in the sun to ripen the wood, or in a temperature of 60 degrees or 65 degrees, and syringe them freely twice a day. If they require shifting, it must be done directly the flowers have fallen. Cuttings taken off close to the plant will root in sand under a glass placed in heat. A. Indica is a plant of great beauty. Stand it in the open air in summer, in a partially shaded position. In winter remove it to a cool part of the greenhouse. The hardy varieties should receive the same treatment as rhododendrons. Flowers in June. Height, 4 ft.
