Prunus × cistena ( N.E.Hansen ) Koehne Prunus × cistena , the purple leaf sand cherry or dwarf red-leaf plum , is a hybrid species of Prunus , the result of a cross between Prunus cerasifera (cherry plum or myrobalan plum) and Prunus pumila (sand cherry). [ 1 ]
The fruit is an edible drupe, 2–3 cm in diameter, ripening to yellow or red from early July to mid-September. They are self-fertile but can also be pollinated by other Prunus varieties such as the Victoria plum. [5] The plant propagates by seed or by suckering, and is often used as the rootstock for other Prunus species and cultivars. [4]

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.
The species' hybrid parentage was believed to be Prunus spinosa and P. cerasifera; [4] [5] however, recent cytogenetic evidence seem to implicate 2×, 4×, 6× [a] P. cerasifera as the sole wild stock from which the cultivated 6× P. domestica could have evolved.
