Cerasus Padus (Bird Cherry).—­An ornamental tree; useful in the shrubbery in its earlier stages, as it will grow in any soil.  It may be increased by seed, budding, or grafting; flowers in April.  Height, 35 ft.

Cerinthe.—­Hardy annuals, suitable for any ordinary soil, and needing merely ordinary treatment.  A grand plant for bees.  Height, 1 ft.

Cestrums.—­Charming conservatory plants, flowering early in spring.  Cuttings may be taken in autumn, placed in small pots in a light compost of peat and sand, and given a little bottom-heat.  The young plants may be topped to form bushy ones.  Re-pot before the roots have filled the small pots, using two parts loam, one part peat, and one part sharp sand.  C. Parqui is suitable for the open if planted in a sheltered position.

Chamaepeuce.—­Half-hardy perennial Thistle plants of little merit.  Any soil suits them, and they may be increased by seed or division.  Flower in June.  Height, 2 ft. to 3 ft.

Chamaerops (Chusan Palm).—­Fine greenhouse plants, delighting in a rich, loamy soil.  Height, 10 ft.

Cheiranthus.—­See “Wallflower.”

Chelidonium.—­This hardy perennial will flourish in any garden soil; flowers in May, and may be increased by division.  Height, 2 ft.

Chelone.—­Charming hardy herbaceous plants.  Succeed well in a mixture of peat and loam or any rich soil.  Increased by division of root, or by seed treated like other hardy perennials.  They are very effective for the centre of beds, or in groups.  Bloom in July.  Height, 3 ft.

Cherries.—­A light, rich soil is the one that Cherries succeed in best, though they will grow in any fairly good dry ground.  The position should be open, but at the same time sheltered, as the blossoms are liable to be cut off by spring frosts.  The planting may be done at any time during November and the beginning of March, when the ground is in a workable condition.  Cherries are often worked upon the Mahaleb stock.  As they have a tendency to gumming and canker, the knife should be used as little as possible, but where pruning is necessary, let it be done in the summer.  If gumming occurs, cut away the diseased parts and apply Stockholm tar to the wounds.  Aphides or black-fly may be destroyed by tobacco dust and syringing well with an infusion of soft soap.  Morello succeeds on a north wall.  Bigarreau, Waterloo, Black Eagle, Black Tartarian, May Duke, White Heart, and Kentish are all good sorts.  Bush trees should stand 10 ft. apart, standards 30 ft.

Cherry (Cornelian).—­See “Cornus Mas.”

Cherry Pie.—­See “Heliotrope.”

Chervil.—­For summer use sow in March, and for winter requirements in July and August, in shallow drills 6 or 8 in. apart.  Cut for use when 3 or 4 in. high.  The tender tops and leaves are used in soups and stews, to which they impart a warm, aromatic flavour.  They likewise give piquancy to mixed salads.
