gracefully ; but the plants generally are 

 not of much garden value. They are of 

 easy culture in rich soil, and may be used 

 as groups in the wild garden. The 

 flowers have an offensive odour. Division.

CISTUS (Rock Rose). Ite Rock Roses 

 are amongst the most beautiful of flower- 

 ing shrubs, but in our country it is only on 

 the lightest and warmest soils and on 

 walls that they may be trusted to survive 

 our winters. Most of the species have 



Chicory. 



been at one time or another in cultiva- 

 tion in this country, but their value is 

 greatly lessened by the recurring severe 

 winters which kill unprotected plants of 

 so many of the kinds. All the 

 species are Old World plants, most 

 of them being natives of South-western 

 Europe ; some extend to North Africa 

 and Asia Minor, and one to the Canary 

 Islands. Many of the species vary 

 a good deal in colour, size of leaves, 

 and not a few appear to hybridise 

 freely. In spite of the fugacious 

 character of the flowers (they do not 

 last, more than one day), their bright 

 colours and the profusion in which a 

 succession is kept up for a considerable 

 time render the Cistuses amongst the 



most welcome of garden shrubs during 

 the summer months. They prefer a dry 

 sandy soil, and, although some grow freely 

 enough in almost any garden soil, they 

 are much more likely to suffer during 

 winter in rich ground. The positions 

 best for them are sunny banks on warm 

 sandy soil, and something may be done 

 by protection and frequently raising and 

 propagating the plant ; but the question 

 as to whether such labour would not be 

 better bestowed on some family of shrubs 

 quite hardy in our climate, may be 

 worth considering save by those who seek 

 collections in face of all difficulties. 

 There are many natural hybrids, some 

 confusion of names, and many more 

 names than distinct plants, this, and the 

 fact that these sun-loving bushes from 

 the south are tender over a large area of 

 our islands makes us limit the species 

 named here to the more distinct and 

 hardier kinds. 



Among the more distinct species are : 

 albiduS) corbariensis, crispus, cyprius 

 hirsutus, ladaniferus, laurifolius, longi- 

 folius, lusitanicus, monspeliensis, parvi- 

 florus, purpureus, salvifolius, Thureti, 

 villosus, with many hybrid forms, one 

 of the best of these being C. Flore?itinus. 



CLADIUM. C. Mariscus is a vigorous 

 native fen plant, 2 to 6 ft. high, in flower 

 crowned with dense, close chestnut- 

 coloured panicles, sometimes 3 ft. in 

 length, the leaves glaucous, rigid, and 

 often 4 ft. long. Worthy of a place on 

 the margin of water. 



CLADRASTIS, the Yellow-wood of 

 N. America. C. tinctoria is a pretty lawn 

 tree of medium size and symmetrical 

 growth, but not a good flowering tree. Its 

 leaves, in autumn, turn to a rich yellow, 

 and remain bright for weeks until cut off 

 by frosts. The white pea-shaped flowers 

 are borne in loose clusters. Syn. Virgilia 

 lutea. C. amurensis is a shrub introduced 

 a few years ago from the Amoor Valley. 

 Its leaves resemble those of the Yellow- 

 wood, but are of thicker texture, 

 not so large, and of a duller green. 

 In late summer it produces a plentiful 

 crop of flowers, even when only a few 

 feet high. The spikes are dense, the 

 blossoms white, and inclined to yellow, 

 and endure a long time. Small bushes 

 flower freely. It is hardy in sandy loams. 

 Leguminosce. 



CLARKIA. These Cahfornian plants

 Order are among the prettiest of hardy 

 annuals, robust, of easy culture, and flower 

 for a long time. There are two species
