ornica.--The white flowers of this evergreen shrub,
which make their appearance in July, are delicately fragrant. The
plant is most suitable for a cool greenhouse, but does well in the
open, in warm, well-drained situations. When grown in pots the mould
should consist of two parts turfy loam, one part peat, and a little
sharp sand. It may be increased by seeds or by cuttings planted in
sandy soil, with a medium bottom heat.

Carrots.--To grow them to perfection carrots require a deep, rich,
sandy soil, which has been thoroughly trenched and manured the
previous autumn. For the main crop the seed should be sown in March,
either broadcast or in rows 18 in. apart. A calm day must be chosen
for sowing, as the seed is very light and liable to be blown about. It
has also a tendency to hang together, to obviate which it is generally
rubbed into some light soil or sand previously to being scattered.
Thin out to a distance of from 4 to 7 in., according to the kind
grown. For early use the French Horn may be sown on a hotbed in
January and February. Keep the surface of the ground well open with
the hoe.

Cassia Corymbosa.--This stove shrub is an evergreen. It should be
grown in a mixture of loam and peat, and may be increased by cuttings
planted in sand under glass in a little heat. It flowers in July.
Height, 3 ft.

Castor Oil Plants.--_See_ "Ricinus."

Catananche.--Pretty hardy biennials that will grow in almost any
soil, and may be increased by seed or division. They bloom in August.
Height, 21/2 ft. to 3 ft.

Catchfly.--_See_ "Silene."

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
