Prunus domestica Prunus domestica Prunus domestica (sometimes referred to as "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 "Prunus cerasifera".; however recent cytogenetic evidence seem to implicate 2x, 4x, 6x "P. cerasifera" as the sole wild stock from which the cultivated 6x prunus domestica could have evolved. This is the most commonly
Prunus simonii is particularly aromatic, much more so than "Prunus salicina", with a comparatively high level of hexyl acetate, which gives apples their aroma. Plant breeder Luther Burbank devoted a lot of work to hybridizing this species with the Japanese plum ("Prunus salicina") and developed a number of cultivars from the hybrid. Of these, the cultivar 'Climax' was particularly notable for its importance to the fruit shipping industry of California. Other influential plum cultivars that Burbank developed with "P. simonii" ancestry include 'Maynard', 'Chalco', 'Santa Rosa', and 'Formosa'. Those two species and the European species "Prunus cerasifera" have contributed the majority of
