Prunus×cistena treeform commonly called purple-leaf sand cherry, is an upright deciduous shrub which has been grafted for additional height. It typically grows 6-10’ tall and 5-8’ wide. It is most noted for its reddish purple foliage that retains good colour throughout the summer. This is a hybrid shrub (P. pumilaxP. cerasifera‘Atropurpurea’) that was introduced in 1910 by Dr. N. E. Hansen at South Dakota State University. Ovate-elliptical leaves (to 2” long) with serrate margins are a distinctive and attractive reddish purple. Fragrant, solitary, white flowers (1/2” across) with pink tints bloom in spring (April) after the foliage emerges. Flowers give way to an often meager production of small blackish-purple fruits (to 3/4”) that mature in July. Fruits are eaten by birds.
Genus name from Latin means plum or cherry tree.
