Cathcartia Villosa.--A beautiful Himalayan poppy, possessing a rich,
soft, hairy foliage and yellow flowers, borne in succession from
June to September. Any light, rich soil suits it, but it requires a
sheltered position. It is propagated by seeds sown in spring. Height,
11/2 ft.
Cauliflowers.--Sow thinly in pans or shallow boxes early in February
and March on a gentle bottom-heat. Make a larger and the main sowing
in the open ground in March, April, and May for autumn cutting. A
sowing should also be made in August for spring and summer use. These
latter should be pricked into a frame or under a hand-glass during the
winter, and in spring planted out so as to stand 30 in. apart. When
the heads appear break some of the large leaves down over them to
afford protection, and during the whole of their growth pour plenty of
water round the stems in dry weather. They require a thoroughly rich
and well-tilled soil to grow them to perfection.
Ceanothus.--A genus of handsome and ornamental evergreen shrubs.
They are free-flowering and suitable for the conservatory or outdoor
decoration if placed in warm situations. They flourish best in peat
and loam, and are increased by cuttings planted in sand and subjected
to gentle heat. Height, 3 ft. to 6 ft.
Cedronella.--Ornamental hardy perennials; will grow in any soil, but
require a little protection in the winter. They produce their deep
purple flowers in June. Height, 3 ft.
Cedrus Deodora.--A beautiful and graceful conifer, its arched branches
being thickly set with long grey-coloured or whitish-green leaves. In
its young stage it makes an exquisite specimen for the lawn. It is
the best of all the Cedars for such a purpose. The usual method of
propagating it is by grafting it on to the common Larch.
Celery.--Sow in February or early in March on a mild hotbed for the
earliest crop. Prick the seedlings off into shallow boxes as soon as
they are large enough to handle, and keep them rather close and warm
until they are established. Towards the end of March prick them out in
rows in a frame, setting them 6 in. apart each way, and early in
May transfer to rather shallow trenches, protecting them from night
frosts. For main and late crops sow in a cold frame in April and plant
out in June or July, 9 in. apart, in trenches 3 ft. distant from each
other, 9 in. wide, and 18 in. deep, pressing the soil firmly round the
roots. Earthing up should be delayed until the plants are nearly full
grown, and should be done gradually; but let the whole be completed
before the autumn is far advanced. When preparing the trench plenty of
manure should be dug into the soil. Water liberally until earthed up
to ensure crisp, solid hearts, and an occasional application of liquid
manure will benefit the plants. During winter protect from frost with
straw, or other suitable material.
Celosia (Feathered Cockscomb).--Sow the seed in early spring in
a warm frame; prick off singly into small pots, and re-pot as they
