524 DEUTZIA. 



THE ENGLISH FLOWER GARDEN. 



DIAXTHUS. 



beautiful Lespedeza bicolor is generally 

 known. It is a slender shrub, graceful 

 when in flower, 6 ft. or more in height, 

 bearing drooping racemes of small Pea- 

 shaped flowers of a carmine-purple colour. 

 It is a native of China and Japan, and 

 hardy enough for open-air culture except 

 in cold districts. It makes a good wall 

 shrub. 



DEUTZIA. The best of the few 

 species in cultivation are D. gracilis and 

 crenata, both common and well-known 



abundance of double snow-white flowers. 

 This is one of the finest hardy flower- 

 ing shrubs, and is called the Pride of 

 Rochester. Deutzias grow in any good soil, 

 best in slight shade ; if too much exposed 

 they are liable to suffer during drought. 

 They should be pruned annually, the old 

 wood being cut away, and the young 

 j growths thinned. 



The species are D. gracilis, Japan. 

 grandiftora, China. macrantha, Himal. 

 mexicana, Mexico. fiarviflora, China. 



Deutzia parviflora. 



shrubs, the first generally seen in green- 

 houses, the second in almost every shrub- 

 bery. D. gracilis, so often grown in pots, 

 is quite hardy, and, under good conditions, 

 makes a dense bush about 2 ft. high, in a 

 free soil flowering as freely as when in 

 pots. D. crenata (commonly called D. 

 scabra) is a much larger bush 6 to 8 ft. 

 high, its leaves large and rough, and, 

 when in flower, its slender stems are 

 wreathed with racemes and panicles of 

 pure-white blossoms. There are two 

 distinct and beautiful varieties of it viz. 

 flore-pleno, with double flowers, tinged 

 with purple, and candidissima, with an 



scabra, Japan. Sieboldiana, Japan, sta- 

 minea, Mountains of India.

 Alps ; or shore plants, such as the Fringed 

 Pink (D. superbus) ; and, so far as our 

 climate is concerned, they are almost at
