Cydonia (Pyrus).—These hardy plants are well adapted for trellis-work, but are more effective when grown as bushes, and flower more freely than when trained to the wall, the bloom often lasting to the winter. They will grow in any soil, and are increased by suckers. Height, 4 ft. and upwards.
Cyperius Alternifolius.—A stove grass which will grow in any soil, but requires a plentiful supply of water. It is increased by dividing the roots. Height, 2 ft.
Cypress (Cupressus).—Among these useful conifers C. Lawsoniana has no superior as a single specimen for the decoration of the lawn. Of free growth and perfectly hardy, it succeeds in almost any soil or situation. C. Fraserii is also hardy, of erect habit, and of a rich glaucous hue. When it attains a good size it is very ornamental. The beautiful silver variegated variety Argenteo Variegata deserves a place in every shrubbery. Nana Alba Maculata is a dwarf globular plant, the slender branches of which are tipped with white, giving it the appearance of being partly covered with snow. Pygmea is a compact dwarf-growing variety suitable for the centre of small beds and for rock-work. Japan Cypresses are elegant little shrubs, one of the finest being Retinospora Ericoides, whose peculiar violet-red leaves contrast charmingly with light green plants. Any of the above may be increased by cuttings. They succeed best in a rich, deep loam, and are improved by thinning out the branches where too thick, and pinching out the stronger shoots where too thin, so as to encourage new growth.
Cypripedium (Hardy Ladies' Slipper Orchid).—This plant is of the simplest culture and is well adapted for pots, ferneries, or rock-work. It is most at home in a well-drained yet moist peaty soil, and kept in a frame or on a shady border, where it will bloom in June. Protect from frost and heavy rains, but never allow the roots to get dry. Height, 1 ft.
Cytisus.—Elegant hardy shrubs with finely-cut leaves and terminal racemes of Pea-shaped flowers in July. They will grow in any soil, and are readily raised from seed or layers. Height, 3 ft. to 4 ft.

Daffodils.—These will grow in any good, cool, moist, well-drained garden soil if sand be put round their roots, but thrive best in a moderately rich loam. They may remain in the ground for years, for large bulbs produce the finest flowers. When the flowering is over the leaves must be allowed to die down, not cut off. Plant from September to December. The top of the bulb should be about 3 in. below the surface, according to its size; 10 in. apart is a good distance. Daffodils are also suitable for pot culture. Plant three to six bulbs, according to size, in a 4-in. or 5-in. pot, using a compost of two parts fibrous loam, one part leaf-mould, and one part sand. Place the pots on a bed of ashes, and cover with 4 in. of cocoa-nut fibre. As soon as top growth has commenced, remove the plants indoors, and give plenty of light and air to prevent them being drawn. Daffodils likewise make a good display when planted on a lawn.
Dahlias.—These attractive plants require a deep, friable soil, not over rich. They may be grown from seed sown on a hotbed in March and lightly covered with fine mould. As soon as they are up give all the air which can with safety be given. When the seedlings are large enough pot them off singly in the smallest-sized pots or round the edges of 6-in. ones. Plant them out at the end of May, 1 ft. apart; they will flower at the end of August. Any that turn out very good had better be propagated by cuttings from the young tops, to save the kind in case the roots should die. When flowering is over take up the young bulbs and treat them as directed afterwards for old tubers.
Another way to propagate them is to place the old tubers in soil over a hotbed early in March. When the shoots are a couple of inches high the tubers may be taken up and divided with a sharp knife. Pot off separately. Water them occasionally with liquid manure, made from guano and powdered charcoal, well mixed with rain water, and plant them out early in May. Give them plenty of room, and tie the branches securely to stakes firmly fixed in the soil. When they have become good bushy plants put a layer of half-rotted manure round each plant. As soon as frost turns their foliage brown take them up, cut off the roots, leaving about 6 in. of stem attached, and plunge them into a box of sand, chaff, or ashes, and preserve them from damp, frost, and heat during the winter.
Daisies (Bellis Perennis).—These pretty, little hardy perennials are very useful as edgings. To grow them to perfection the ground should be highly manured, and the roots divided every year, planting them out 6 in. apart in a cool, shady situation. October is a suitable time for transplanting. They flower continuously from February to July. Height, 6 in.
