SHRUBBY A^D SUB-SHRUBBY FLOWERS. 



115 



There are other species, with yellow, red, and purple 

 flowers, which, though individually ephemeral, follow each 

 other in long and constant succession during the finest 

 summer months. Some of our native trailing species 

 make exceedingly elegant rock-plants. The Cistuses are 

 of various degrees of hardiness, but all like a warm, well- 

 drained, chalky soil. Multiply by suckers, cuttings, and 

 seeds sown on a hotbed in spring. 

 Clematis. — See Virgin's Bower. 



Clianthus puniceus. — A very handsome half-creeping 

 shrub, with pinna-ted leaves, from j\ T ew Zealand. It is 

 usually kept in pots, in a greenhouse, in a mixture of 

 loam and rotten hotbed ; but will stand the winter trained 

 against a wall (especially near the sea), with the protec- 

 tion of thick mulching and matting in winter. There, its 

 bunches of large pea-like scarlet blossoms are really 

 splendid. Increase by cuttings and suckers. 



Coronilla glauca. — A pretty, yellow-flowered, papilion- 

 aceous pot-shrub, with sea-green pinnated leaves, useful 

 for parlour-windows, because its plum-scented blossoms 

 are gay throughout the winter. Native of the shores of 

 the Mediterranean ; is increased by seeds, cuttings, and 

 layers. 0. Emerus is hardier and more robust, with red 

 flower-buds and yellow open flowers. It is sometimes used 

 to make clipped fences, where the resistance of thorns is 

 not required. If shorn in spring, will flower in autuinn. 



Cytisus Laburnum, or False Ebony, from its handsome 

 dark heart-wood. — Almost a tree; well known for its 

 bunches of drooping golden blossoms in spring. Hardy, 

 vigorous, and increased abundantly by seed ; is used as a 

 stock whereon to graft other more delicate Cytisuses and 

 allied species ; amongst which are G. nigricans, sessili- 

 folius, capitatus, Austriacus purpureus (with pinky- 

 violet flowers), and alius, Spartium album, or Spanish 

 Eroom. On one of the grass-plots in Kew Gardens 

 there grows a curiosity interesting to hybridists, — a 

 Laburnum between Cytisus nigricans and C. Laburnum. 

 The plant has put forth one branch of nigricans and one 

 of Lalumum ; the rest is hybrid.
