Prunus domestica

Prunus domestica is a species of flowering plant in the family Rosaceae. A deciduous tree, it includes many varieties of the fruit trees known as plums in English, though not all plums belong to this species. The greengages and damsons also belong to subspecies of P. domestica.

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