A YEAR'S GARDENING 



CAPE FORGET-ME-NOT. See Anchusa. 



CAPE HYACINTH. See Galtonia. 



CAPE MARIGOLD. See Dimorphotheca. 



CARNATION. See Dianthus. 



CASSIOPE. A beautiful little Alpine heather bush, eminently 

 suited for the Rock or Alpine Garden. It delights in a well-drained 

 peaty soU and may be propagated either by division or by pegging 

 down; but it is somewhat difficult of cultivation, as while needing 

 light and moisture it must have free drainage and be shaded from 

 any scorching sun. 



CASTOR-OIL PLANT. See Ricmus. 



CATANANCHE {Cupid's Dart). A hardy perennial, growing 

 some i8 inches to 2 feet high, and an old favourite as a border plant. 

 The C. ccerulea, with its bright blue flowers, is that usually grown, 

 but there is a white variety and a bi-coloured blue and white. All 

 may easily be raised from seed and require no special soil. 



CATCHFLY. See Silene. 



CELOSIA {Cockscomb). A plant which is very useful for green- 

 house decoration by reason of its graceful plumes and feathered 

 sprays of inflorescence, and in a well-protected spot it will even 

 flourish in the open. Seed should be sown in heat in the spring, the 

 seedlings being pricked off as soon as possible and continued in heat 

 until the crowns appear. They need a good rich soil and plenty of 

 water. There are several varieties of various shades — ^golden, 

 crimson and rainbow. 



CELSIA. C. cretica, the Cretan MuUein, is a half-hardy biennial, 

 but is more usefully treated as an annual. Its golden sprays of 

 flowers and shining buds make it a pretty plant for the greenhouse, 

 and in warm situations it will thrive in the open. 



CENTAUREA. A family which includes many familiar flowers, 

 such as the Cornflower, Sweet Sultan and Golden Knapweed. While 

 some of the varieties are wisely treated as annuals most of them are 

 perennial and quite hardy. C. habylonica, for instance, is a hardy 

 perennial, and with its silvery leaves and tall shoots of yellow flowers, 

 ranging from 8 to 10 feet high, has a fine effect in a suitable position. 

 It is easily raised from seed. C. Cyanus (Cornflower) is a native 

 annual, sowing itself freely, and often producing the best plants in 

 that way; there are many varieties of colour — white, sky-blue, rose 

 and dark purple. C. moschata (Sweet Sultan) is an annual well
