General Description
Sand Cherry is a low shrub with prostrate to ascending branches that are 1-4 dm tall. The alternate, narrowly elliptic leaves are 4-7 cm long, have petioles, and are 5-14 mm long with entire to toothed margins. The twigs are red but become gray with age, and the leaves are dark green and glabrous above but paler below. Clusters of 2-4 flowers occur in the axils of the expanding leaves. Each flower has a bowl-shaped, 5-lobed calyx that is 2-4 mm high and which holds the ovary and 25-30 stamens. The 5 separate, white petals are 6-8 mm long. The globose cherry is dark purple and 13-15 mm long.

Mature fruit in June.
