Prunus americana has often been planted outside its native range and sometimes escapes cultivation.[9] It is commonly confused with the Canada plum (Prunus nigra), although the fruit is smaller and rounder and bright red as opposed to yellow. Many cultivated varieties have been derived from this species. It forms an excellent stock upon which to graft the domestic plum.[10][11]
