Oklahoma Plum, Sour Plum, Sand Plum
Prunus gracilis


Oklahoma plum prefers a sunny exposure and the dry slopes of exposed hills and sparse woods, fencerows and fields from the Texas panhandle into east Texas, Oklahoma, Kansas, Arkansas and Tennessee. It is a straggling, thicket-forming shrub having slender, slightly spreading stems. It flowers in March, prior to leafing out. The flowers are abundant and showy, several to a cluster on lateral umbels. Its red fruits mature from June through August, displaying a waxy greyish coating (bloom). Although quite pulpy, it is considered to be of poor eating quality as a fresh fruit. However, they were dried by Native Americans for winter use. Oklahoma plum, which is variously known as sour plum or sand plum, was introduced into cultivation in 1916.
