Crepis (_Hawkweed_).--An interesting hardy annual. It merely requires
sowing in spring, and will grow in any soil. The flowers are produced
in June. Height, 1 ft.
Cress.--Sow at intervals of a week from March to September in the open
ground, and during the winter months in frames. A shady position is
most suitable. By these frequent sowings, and by often cutting over
such as readily renew a bottom growth, a constant succession of tender
shoots is obtained.
Crocus.--Among our earliest spring flowers. These will grow in any
garden soil, but prefer rich, sandy earth. Plant in October or
November, 3 in. deep and 2 in. apart. Take the roots up every second
year, and plant the small off-sets in a nursery bed for two years,
when they will be fit for the beds or borders. Protect the bulbs from
mice, as they are very partial to them, especially in winter.
_Indoor Culture_.--Select strong bulbs of the seedling varieties, and
plant them in succession, commencing early in autumn, in good, rich,
sandy soil. A liberal supply of water is necessary during the blooming
season, but perfect drainage must be secured. They grow well in bowls
filled with wet moss or sand. Height, 6 in. (_See also_ "Colchicum.")
Crotons.--Fine-foliaged hothouse plants. A mixture of peat and sandy
loam suits their growth, and they require a good amount of light to
properly colour their leaves, with a night temperature of 70 degrees.
Crowea Saligna.--Charming greenhouse evergreen shrubs, which send
forth their purple flowers in September. They grow best in loam and
peat. Cuttings may be struck in sand under bell-glasses. Height, 3 ft.
