THE BOOK OF GARDENING. 



Rochester has double white flowers ; it is of erect habit, and 

 very distinct. D. c. punctata deserves a place on account of its 

 pretty variegated foliage — pale green, striped with white and 

 blotched with dark green. D. parviflora is the first to flower 

 in the open air; it is a native of Northern China, and makes 

 a dense bush 5 ft. high ; the creamy-white flowers are produced 

 in profusion. D. corymbiflora is a new kind, of elegant habit 

 and wonderfully free-flowering ; the pure white flowers are borne 

 in graceful panicles, and last in good condition for a long 



time ; a very valu- 

 able addition. D. 

 gracilis is the most 

 generally cultivated 

 member of the genus ; 

 it is perfectly hardy, 

 of slender growth, 

 2 ft. high, very free- 

 flowering, and valu- 

 able for forcing. 

 Another dwarf- 

 habited kind, but of 

 stronger growth than 



WKfJtf ~ Tit <'2l tliyW si -D- gracilis, is D. 



■~\-*Mmk. *i— « Lemoinei, also use- 



ful for forcing ; it 

 is a very handsome 

 variety, and excep- 

 tionally floriferous, 

 the small white 

 flowers being borne 

 in compact trusses. 



DrERViLLAs. — Few 



dwarf-growing shrubs 



are more easily 



grown, or create 



better effect, than 



the Diervillas (Wei- 



gelias or Bush 



Honeysuckles). 



Planted in beds on 



the turf, or in front 



of taller-growing- shrubs in the border, they succeed and 



look well. They like rich, well-drained soil, and an annual 



top-dressing of leaf-mould increases the floral display. The 



thin, flowerless shoots should be removed. A good selection 



should include some or all. of the following : amabilis is of 



good growth, and bears an abundance of rose-coloured flowers 



in early summer. Van Houttei (Fig. 246), carmine shaded red
