always be kept moist and cool, and the plants disturbed as little as
possible. A top dressing of fresh soil may be given each winter, and
the plants protected from frost by binding straw round the stems.
Campanula.--A showy genus of plants, mostly hardy perennials, which
need no special treatment. They are readily raised from seed, or
division of roots. The less hardy kinds may be sown on a hotbed or in
the greenhouse, and when large enough potted off. Campanula Mayii is a
grand plant for hanging baskets, and also grows well trained up
sticks in a pyramidal form. A rich, gritty soil suits them all. The
tall-growing varieties make fine pot-plants. Flower in July. Height, 1
ft. to 5 ft.
Canary Creeper (Tropaeolum Canariense).--This is eminently suitable
for trellis-work or for walls. Its elegant foliage and bright yellow
flowers make it a general favourite. It may be raised from seed on
a hotbed in spring, gradually hardened off, and planted out in May.
Height, 10 ft.
Candytuft (Iberis).--Very pretty hardy annuals. Sow the seed in
autumn in a light, rich soil, or in spring if a less prolonged
flowering season will give satisfaction. Bloom in May or June. Height,
1 ft.
Canna (Indian Shot or Hemp).--For pot-plants on terraces, gravel
walks, and such like places, few things can equal and none surpass
Cannas. They are half-hardy perennials, and may be increased from
seed or by dividing the roots late in autumn, allowing them first to
partially dry. File the tough skin off one end of the seed, and steep
it in hot water for a few hours before it is sown, then stand it in a
hot place till it has germinated. Harden off and plant out, or shift
into larger pots in June, using a rich, light soil. Lift and store the
roots in autumn in the same way as Dahlias. Different kinds flower at
various seasons, so that a succession of bloom may be had throughout
the year. Height, 2 ft. to 10 ft.
Cannabis Gigantea (Giant Hemp).--This half-hardy Hemp is grown for
its ornamental foliage, and is treated as above described. Height, 6
ft.
Canterbury Bells.--Showy hardy biennials, which may be raised from
seed sown in the spring. Transplant in the autumn to the border where
they are intended to flower. The seed may also be sown in a sheltered
position in August or September. Flower in July. Height, 2 ft.
Cape Primroses.--See "Streptocarpus."
Caprifolium.--See "Honeysuckle."
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
