Deutzia × lemoinei Bois

A small group of hybrids between D. gracilis and D. parviflora raised by Lemoine of Nancy. The typical form of the cross – ‘Lemoinei’ – was raised in 1891. It is an erect shrub up to 7 or 8 ft high, with glabrous young shoots, and lanceolate leaves, 11⁄2 to 4 in. long, 1⁄2 to 11⁄4 in. wide, sharply toothed, long-pointed; the upper surface has minute star-like hairs, beneath it is almost glabrous. Flowers pure white, 5⁄8 in. across, produced in erect corymbs. For forcing into flower early this is a very valuable shrub, more beautiful and effective than gracilis, and in that state was very popular at spring flower shows. Out-of-doors, at least in low-lying localities, it rarely has a chance to do itself justice, owing to the destruction of its flower-buds by unseasonable frosts. Its natural flowering time is May and June. See further under D. amurensis.
