Description

Small white flowers clothe the leafless branches in April, presenting the entire shrub as a white cloud. Leaves are narrow-elliptic or lanceolate, narrowed at both ends, almost entire, 1 1/2 to 1 3/4" long, 3/8"wide, soft sea-green, appressed silky hairs beneath. Plant a rather dense shrub with arching stems; reaches 4-5' in height and width. In the author's opinion, this cultivar is far superior to S. xarguta, and S.thunbergii.
