Zl6 THE NURSERY LIST. 



Cordyline (Dracaena, Dragon-tree). Liliacecz. 



Seeds, if fresh ones are obtainable, for many of the 

 species. The varieties (as the greenhouse drac:enas), by 

 cuttings. Chinese layers (Fig. 34) succeed fairly well. 

 The stems of old plants may be cut up in pieces i or 2 

 inches long, and placed at any season in cocoanut fiber 

 or light soil, in the bottom heat of a propagating house. 

 The tops of the plants will also strike as cuttings, and the 

 fleshy base of the stem is sometimes removed and used 

 for propagation. Root cuttings do well in a moderate 

 heat, and are much used. (See Fig. 63.) 



Corema (Portugal Crakeberry, Crow berry). Einpctracea;. 

 Seeds. 



Coreopsis, Calliopsis. Compositor. 



The hardy annuals, which are largely grown under the 

 name of calliopsis for sunniier ornamentation, by seeds. 

 which should be sown in early spring in a gentle heat, or 

 outside later. The perennials are propagated also by 

 division of the root in autumn or spring, or during the 

 summer by young cuttings, which will strike freely in a 

 coli.liVanie. 



Coriander [Coyiandrmn salii'uin\. l_'mbcllifcra:. 



Seeds sown in fall or spring. 

 Corn. See Maize. 



Corn Salad (\'alerianella, several species'). I'a/t'riaiiacfir. 

 Seeds sown in spring, summer or autumn. The plants 

 mature ciuickly. 



Cornus (Dogwood, Osier). Comae ca-. 



Increased by seed, suckers of soft wood, layers or cut- 

 tings. The herbaceous species, C. Canadensis and C. 

 Sueciea, may be increased by division, as also by seeds. 

 Tile willow-like cornuses grow from cuttings of ripe wood, 

 C sfolonifcra and its kin by layers or stolons. Named 

 varieties and some species are budded in many cases, 

 especially all the weak-growing sorts. Cornus Mas, 

 raised from seed, is the favorite stock. Shield-budding in 

 late summer and veneer-grafting are most successful. A 

 cutting is shown in Fig. 60. 



Coronilla. Le'e^nniijiosie. 



By seeds sown as soon as ripe. The hardy species by
