A SEEDLING CINERARIA 

 ready for pricking off.

and spring, it is a most valuable plant. Good strains of seed are 

 rather dear, but they are worth their cost. They may be sown in 

 May and June similarly to Calceo- 

 larias, pricked off into boxes, then put 

 singly in small pots, and finally trans- 

 ferred to 6-in., 7 -in., and 8 -in. pots, in 

 which they will flower. They must have j 

 cool, airy conditions in summer, and a 1 

 frame suits them. They may even be 

 stood in the open air. Green fly (see 

 Aphides) must be kept away. Cineraria 

 maritima, a dwarf plant with silvery 

 foliage, is often used in bedding. It may 

 be raised from seed in spring. Such 

 other species as are grown are now called 

 Senecios by botanists, but only one is 

 much used in gardens, and that is 

 cruenta, a greenhouse perennial growing 

 about 2 ft. high and with purplish 

 flowers in summer (see the Botanical 

 Magazine, t. 406). 



Cinnamomum, Cinnamon (cinnamo-mum, from kinamon (Arabic). 

 Ord. Laurineae). Unimportant horticulturally, but important 

 economically, as C. zeylanicum yields cinnamon and C. Camphora 

 gives camphor. 



Cinquefoil. See Potentilla. 



Cissus (clss-us, from kissos, Ivy, in allusion to the habit. Ord. 

 Amepelideae) . One species, discolor, is grown. It produces 

 greenish flowers in September, but is chiefly grown for its handsome 

 leaves, which are velvety green marked with white (see the Botanical 

 Magazine, t. 4763). It may be grown in peat and loam in equal 

 parts, with sand, on the roof of a hothouse. Propagation is by 

 cuttings of side shoots under a bell-glass in heat. 



Cistus, Rock Rose (cis-tus, from kiste, a box, alluding to the shape 

 of the seed vessel. Ord. Cistineae). Brilliant shrubs, suitable for 

 the rock garden, flowering in June, and thriving in warm, sunny, 

 sheltered places. They like well-drained, sandy soil. Propagation 

 is by seeds in spring, in a frame or greenhouse, or by cuttings in 

 May and layers in late summer. The following are the best: 

 albidus incanus, white; crispus, purple; cyprius, white; and 

 salvifolius, white, all 2 ft. high; and ladaniferus, white, and its 

 varieties, such as maculatus, spotted; laurifolius, white; lusitanicus, 

 white or yellow; and longifolius, white; all of which grow 4 ft. 

 high. 



Citrus (cit-rus, from Citron, a town in Judea. Ord. Rutaceae). A 

 genus of little value from the garden point of view, but very im- 

 portant economically, giving, as it does, the Orange (C. Aurantium), 

 the Shaddock (C. decumana), the Citron (C. medica), the Lime 

 (C. medica Limetta), and the Lemon (C. medica Limonum). The 

 Otaheite Orange is sometimes grown as a pot plant (see Fruit, p. 154); 

 nice dwarf plants can be grown in 6-in. pots, and low standards 

 in 8 -in.
