Lemoine deutzia was created in 1891 by Victor Lemoine at his nursery in Nancy, France, crossing the Asian species Deutzia gracilis and Deutzia parviflora. The hybrid name honors the nurseryman himself, and the plant has since proved to be one of the most enduring contributions from a nursery responsible for dozens of beloved garden plants. It is the hardiest deutzia in cultivation, dependable into USDA Zone 5 and viable in warmer pockets of Zone 4, which extends its usefulness across a wider geography than most of its relatives.

The shrub grows dense and upright, 5 to 7 feet tall, with slender brown stems and exfoliating bark that provides quiet winter interest. The medium green foliage turns yellow in fall before dropping. Pure white flowers appear in rounded clusters in late spring — smaller individually than those of some relatives, but produced in such quantity that the effect is equally generous. It tolerates a wide range of soils and maintains itself well with a post-bloom pruning to remove dead wood and keep the shape tidy. For an informal hedge, woodland border, or cottage garden backbone, Lemoine deutzia rewards the gardener who gives it room to do what it does naturally.
