''Prunus pumila'', commonly called sand cherry, is a North American species of ''cherry'' in the rose family. It is widespread in eastern and central Canada (from New Brunswick west to Saskatchewan) and the northern United States (from Maine to Montana, south as far as Colorado, Kansas, Indiana, and Virginia, with a few isolated populations in Tennessee and Utah).〔〔(Biota of North America Program 2014 county distribution map )〕 It grows in sandy locations such as shorelines and dunes. ''Prunus pumila'' is a deciduous shrub that grows to 10–40 cm (4-16 inches) (rarely to 180 cm (6 feet)) tall, forming dense clonal colonies by sprouts from the root system. The leaves are leathery, long, with a serrated margin. The flowers are produced in small clusters of two to four together, diameter, with five white petals and 25–30 stamens. The fruit is a small cherry diameter, ripening dark purple in early summer.〔(【引用サイトリンク】url=http://FieldGuide.mt.gov/detail_PDROS1C160.aspx )〕〔Huxley, A., ed. (1992).
