These early and free-blooming deciduous shrubs are very useful in the border, particularly crenata and its varieties, of which the double white, flore pleno, is one of the best. Eburnea is a new ivory variety of crenata. They flower profusely, indeed, if pruned as advised in Chapter 13. they will be wreathed in blossom in spring. The bright canes are not without ornamental importance. Height up to six feet. Gracilis is smaller and is often reserved for pot culture; there are forms of it called hybrida (or gracilis) rosea, carminea, campanulata, eximia, multiflora and venusta. Lemoinei, which flowers later, is a hybrid; height about two feet; there are forms of this called Apple blossom, Boule de Neige, Boule Rose, Avalanche and compacta. Corymbiflora, white, height up to five feet, and its garden form erecta, must be considered. Discolor is a species from China, growing up to three feet high, but compact, and bearing rosy white flowers in clusters on the whole length of the arching one-year old wood in June. Discolor purpurascens, with comparatively long toothed leaves, dark above and pale below, is a form of it, as is fasciculata, rose tinted. Discolor floribunda and discolor grandiflora are hybrids between discolor and gracilis. Discolor major comes from Central China and has clusters of white flowers in June. Kalmiaeflora, three feet, silvery rose, is a hybrid (discolor purpurascens and parviflora). Parviflora, white, flowers in clusters, is very early. Myriantha, a slender shrub with white flowers in June, is a hybrid (corymbiflora crossed with parviflora). Scabra, height up to six feet, has white flowers in late spring. There is confusion between this and crenata, and the double white and double purple scabras of the nurseries are certainly forms of crenata, not of scabra, which is a stronger grower. Ordinary soil.
