Capsicum.--Sow early in March in well-drained pots of rich, light,
free mould; cover the seed with 1/2 in. of soil, and keep it
constantly moist at a temperature of 65 degrees. When strong enough
to handle put two or three plants in a 5-in. pot, and replace them in
warmth. Keep them rather close till established, then shift them into
7-in. pots. When established remove them to a cold frame and harden
off. Plant out at the end of May in a warm situation. Keep them well
supplied with water in dry weather and syringe the leaves. By stopping
the shoots they become nice, bushy shrubs. Flower in July. Height,
1-1/2 ft.

Cardamine Pratensis (_Cuckoo Flower, or Milkmaid_).--This hardy
perennial thrives in a moist, shady situation. It produces its purple

division. Height, 1-1/2 ft.

flowers in May, and is easily raised from seed. Height, 1-1/2 ft.

Cardoons.--Sow two or three seeds together in clumps 1 ft. apart, in
trenches prepared as for Celery, in April or May. When 6 in. high pull
up the superfluous plants, leaving the strongest one in each case.
When they have attained the height of 1-1/2 ft, tie the leaves lightly
to a stake and earth-up the stem. Keep them well supplied with water,
adding a little guano. They will be ready for use in September.
Another sowing may be made in June for a spring crop.

Carduus (_Milk Thistle_).--Coarse hardy annuals; somewhat ornamental,
but are hardly more than weeds. They grow freely from seed, and flower
from June to August. Height, 2 ft. to 4 ft.
