Cordyline, Club Palm (cordyll-ne, from kordyle, a club. Ord. 

 Liliaceae). These plants, which are related to Dracaenas, are 

 grown for their foliage, which is slender and graceful. Australis 

 and indivisa are the two most popular species ; there are variegated 

 forms of both. They are sometimes planted out of doors, but they 

 are not hardy. Loam, with a fourth of leaf mould, and sand, suit 

 them. They are propagated by suckers. Tall, leggy plants may 

 be decapitated, the tops struck in bottom heat, and the stems laid 

 in moist soil or cocoa-nut fibre refuse in heat to induce shoots to 

 break for cuttings. See Dracaena. 



Coreopsis, Calliopsis (coreop-sis, from koris, a bug, and opsis, like, 

 in allusion to the seed. Ord. Compositae). Useful plants, the 

 annual species of which are generally grown under the name of 

 Calliopsis (see Annuals). Lanceolata is a good hardy perennial, 

 growing about 2 ft. high and bearing yellow flowers in summer (see 

 the Botanical Magazine, t. 2451). Grandiflora (syn. longipes) is 

 also a good perennial with yellow flowers in summer. Drummondii 

 and tinctoria are the best of the annuals ; both have red and yellow 

 flowers. Grantii, yellow, blooms in the greenhouse in winter. 



Coris monspeliensis. A pretty rockery plant (Ord. Primulaceae) , 

 which grows about a foot high, and produces lilac flowers in June 

 (see the Botanical Magazine, t. 2131). It likes a dry, sunny spot, 

 v,ith sandy peat. It is easily raised from seed sown under glass in 

 spring. 



Corn Flag. See Gladiolus, under Bulbs. 

 Cornflower. See Centaurea and Annuals. 

 Cornish Moneywort, Sibthorpia europaea. 

 Corn Salad. See Kitchen Garden. 



Cornus, Dogwood (cor-nus, from cornu, a horn, alluding to the 

 hardness. Ord. Cornaceae). Deciduous shrubs, much esteemed 

 for the beauty of their foliage and the brightness of the bark. Alba, 

 a Siberian species, has white flowers in July. Spathi and variegata 

 are popular varieties of it. Capitata has white flowers in August; 

 it is not quite hardy; fruit sometimes ripens on a wall in Great 

 Britain, but it is not edible; this is the Benthamia fragifera of the 

 Botanical Magazine, t. 4641. Florida has white flowers in spring; 

 it is one of the best, and there are good varieties in rubra and 

 pendula. Mas (syn. mascula), the Cornel or Cornelian Cherry, has 

 yellow flowers in February (see the Botanical Magazine, t. 2675). 

 There are several varieties of it, aurea elegantissima being one of 

 the best. Sanguinea is the common British Dogwood; the berries 

 are black; it is often planted for winter effect, the red branches 

 being bright. There are one or two herbaceous perennials, the best 

 being canadensis (see Botanical Magazine, t. 880), with yellowish 

 flowers in summer, suitable for the rock garden where peat can be 

 given. The shrubby Dogwoods need no special soil, but they do 

 not like a dry spot. Propagation is by seeds, layers, cuttings, and 

 division.
