Culture
Easily grown in average, medium moisture, well-drained soil in full sun to part shade. Best flowering in full sun. Wide range of soil tolerance. Prefers moist, humusy soils. Stems are somewhat short-lived, and annual pruning of dead branches is usually necessary. Prune in spring immediately after flowering.
Noteworthy Characteristics
Deutzia × lemoinei is the result of a cross between D. gracilis and D. parviflora. It grows 5-7’ tall with upright branching. Tiny white flowers (to 5/8” across) appear in late spring in large panicles or corymbs (to 3” long) which cover the shrub for about two weeks. Opposite, toothed, long-pointed, elliptic to lanceolate, green leaves (to 4” long) are hairy beneath. No fall color.
Genus name honors Johan van der Deutz (1743-1788), amateur botanist from Amsterdam.
The hybrid name lemoinei honors Victor Lemoine (1823-1911), French nurseryman who introduced this plant in 1891 from his nurseries at Nancy, France.
Problems
No serious insect or disease problems. Aphids and leaf spots may appear.
Uses
