Discussion

Deutzia ×lemoinei Lemoine, the hybrid between D. parviflora and D. gracilis, often has been grown in the flora area and is considered one of the hardiest cultivars (A. J. Rehder 1940; M. A. Dirr 1998). Three varieties of D. parviflora are recognized in China; plants in the flora area seem closest to var. parviflora.
