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/
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.
