also by division of the roots in spring or early 

 autumn. Grandiflora should be raised from seed 

 frequently, as old plants often die out. A light, 

 but rich, sandy soil suits.

CORETHROGYNE. 



A small genus of Californian plants (onl. Com- 

 posite), allied to the Aster, and needing the same 

 cultivation, except that they require a little pro- 

 lection in winter. The one introduced is obovata, 

 1', August, pink, which is almost covered with a 

 white wool (si/n. spathulata). Others are cali- 

 fornica (syn. incana), and filaginifolia (syns. to- 

 mentella and virgata). 



CORIANDRUM. (COBIANDBK.) 

 The Coriander is C. sativum, a hardy annual 

 plant (ord. Umbellifene"), which grows about 2' 

 high, and bears white flowers in June, or later, 

 according to the time when sown. Sow seeds in 

 warm positions in spring and autumn ; if leaves 

 are wanted for flavouring soups, or for salads, 

 sow at intervals. The seeds are used for confec- 

 tionery. Common soil. 



CORIARIA. 



Ornamental hardy or half-hardy shrubs (onl. 

 Coriariese), which grow in common soil, and are 

 propagated by layers, suckers, or cuttings in 

 sandy soil under a bell-glass. The hardiest is 

 myrtifolia, (!', June, green. Other species are 

 japonica, 5', June, rose; nepalensis, 10', May, 

 brown ; ruscifolia, 3', June, green ; and terminalis, 

 which mainly differs from nepalensis in having 

 flowers at the ends of the branches. 



CORIS. 



The only Coris in cultivation is monspeliensis 

 (prd. Prirnulacese), which is <i" high, flowers in 

 June, and has pretty, bright lilac flowers with 

 orange anthers. It needs a dry, sunny place on a 

 well-drained rockery, in light, sandy soil. Propa 

 gated by seeds sown in a frame in March. 



CORK. 



The hard, outer bark of a species of Oak (Quercus 

 suber) much used for various domestic purposes. 

 Sheets of virgin coik, so called because they have 

 not been used, are in great request for various 

 phases of decorative gardening. They are much 

 used for covering window boxes, forming pockets 

 for Ferns and other plants, and many kinds of 

 rustic work. Many plants form cork on the 

 surfaces of their stems, and this is the true nature 

 of the substance with which a healthy plant covers 

 wounds or abrasions of the epidermis. 



CORNFLOWER (fee also CEXTAUKEA). 

 The popular name of Centaurea Cyanus (;</. 

 Coinpofiue). also sometimes named t'yamis cyanus. 



CoKEOl'SIS LANCEOLATA. 



The wild plant bears flowers of one of the love- 

 liest shades of blue that we have amongst a field 

 of corn or in the garden. To distinguish it from 

 other Cornflowers it is often termed the Bluo 

 Cornflower. Other names for it are Blue-bottle, 

 Blue-cap, and Blue-bonnet. It is the German 

 national emblem. In gardens a large number of 

 varieties have been raised, ranging from white to 

 the deepest blue and purple, with all intermediate 

 shades. Victoria Dwarf Blue is a recently raised 

 strain of dwarf (9") compact habit, with .-mall. 

 deep azure blue heads. It is easily raised from 

 seeds sown in the open ground in any ordinary 

 garden soil at the end of March or beginning of 

 April, when it may be termed an annual. If .-own 

 as soon as the seeds are ripe, the seedlings will 

 stand the winter like a biennial, and flower early.
