COSMOS. 



Beautiful annual or perennial plants (urd. Com- 

 positse), prized for beds, borders, or conservatory 

 decoration, and for cut flowers. Includes Cosmea.

COSSINEA.

 ing in the stove. It grows well in well-drained 

 loam and peal, and may be propagated by cuttings 

 under a bell-glass in heat.

COSTMARY. 



Though seldom cultivated nowadays, except in 

 country cottage gardens for its medicinal virtues, 



Co-tmary was formerly used largely in salads be- 

 cause of its bitter tnste and aromatic odour. Its 

 botanical name is Tanacetum Balsamiia, and it 

 belongs to what is popularly known as the Fever- 

 few group of the order Composite. Under cultiva- 

 tion it succeeds best in a moderately dry position. 

 Stock is increased by dividing the roots in autumn 

 or sowing seeds in spring. 



COSTUS. 



A genus (urd. Scitamineae) of stove herbaceous 

 perennials, some of which produce strikingly hand- 

 some flowers. Division is the readiest mode of 

 increase, and the plants grow well in fibrous loam 

 three parts, peat one part, and coarse sand.

COTONEASTER. 



A valuable genus of about fifteen species of 

 hardy shrubs or small trees (nrd. Rosace*), many 

 of which are of great value for covering walls in 

 either sunny or shady positions. The smaller 

 species are fine on rockwork. Propagated by 

 seeds sown as soon as ripe in nursery beds, by 

 cuttings in spring or autumn, and by layers. 

 Cuttings strike readily in the open or under a glass, 

 without heat. Grafting on the commoner species 

 is also practised. Common garden soil

COTTON. (See also GOSSYPIUM.) 



Among textile fabrics cotton takes n foremost 

 place, and its production affords occupation to 

 many thousands of people. The material is wow-n 

 from the silky-white, hairy covering of the seeds 

 of .several species of Gossypium, but the one 

 mostly cultivated is herbaceum. which is repre- 

 sented by several varieties, notably barbaden-r, 



I'msus Lii/iii/n'rila (nee Gnat Moth).
