Discussion

The purple-leaved, pink-flowered cultivars of Prunus cerasifera are especially popular for ornamental use. The earliest purple form was introduced into European gardens about 1880 by M. Pissard, gardener to the Shah of Iran. Prunus cerasifera is widely used as a rootstock for commercial plums.
