Purple-leaf sand cherry is an upright deciduous shrub that typically grows 6-10’ tall and 5-8’ wide. It also may be trained as a small tree. It is most noted for its reddish purple foliage that retains good color throughout the summer. This is a hybrid shrub (P. pumila x P. 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. Specific epithet means baby in Sioux language.
Susceptible to a large number of potential insect and disease pests, often resulting in an abbreviated life span of less than 10 years. Trunk cankers and borers can be particularly harmful. Japanese beetles can do significant damage to the foliage. Potential additional insects include aphids, scale, leafhoppers, caterpillars and tent caterpillars. Potential diseases include leaf spot, die back, leaf curl, powdery mildew, root rot, honey fungus and fireblight. Spider mites may also be troublesome.
Reddish purple foliage makes this an excellent accent or specimen. Borders, screens, hedges, entranceways and foundations.
