Sand cherry, also called beach plum, "cerise de sable" (Fernald 1923), or dwarf American cherry, is a diffusely branched, low growing (0.5 to 3 m tall, depending on variety and habitat) to sometimes decumbent or prostrate shrub (Fernald 1923, Gleason 1952, Lamson-Scribner 1891). Older stems develop a grayish, glabrous bark, while younger twigs are often tannish- to reddish-brown or brown.
