50 ROCK AND WATER GARDENS 



they rarely do well except in the southern counties, and 

 even there they are liable to be destroyed during a severe 

 winter. They are easily propagated, and a stock of new 

 plants can be raised from time to time, so as to make 

 good any losses. The flowers last but a single day, but 

 are borne in such profusion that this peculiarity is hardly 

 noticeable. C. laurifolius and C. cyprius are among the 

 best. 



The Genistas (Rock Broom) are a large family, and 

 contain many varieties for the rock garden. In the 

 majority of species the twigs assume a pendent habit, and 

 the effect of the cascades of yellow blossoms streaming 

 down the rock slopes is delightful. G. germanica is free 

 flowering, and forms a shrub of moderate dimensions, 

 G. pilosa, occasionally occurs naturally in England, 

 bearing its yellow flowers in May and June. The double 

 form of G. tinctoria, G. aspalathoides, G. praecox and 

 G. Andreana are among those from which a choice may 

 be made. All the Genistas are readily increased by seed, 

 are indifferent as to soil, and need transplanting before 

 the roots become too coarse and straggling. 



Owing to the practice of crowding the hardy Junipers 

 among free growing evergreens in the shrubbery, their 

 value is seldom realised. When grouped together in the 

 rock garden it will be seen that they are by no means 

 unworthy, the common Savin (J. Sabina) having a 

 decided beauty in its graceful, feathery branches. J. 

 prostrata is a good sub-variety. 



On warm, sunny banks a few plants of Lavender and 

 Rosemary will afford those silvery half tones which are 

 of such value in the composition of colour effects. The 

 older bushes look best, the trim symmetrical form of 

 the young plants having given place to a freedom of 

 gnarled and twisted branches, lightly flecked with 

 glaucous leaves. Both the white and blue Lavenders 

 are worth cultivation. Apart from other reasons there
