Prunus cerasifera

Prunus cerasifera is a species of plum known by the common names cherry plum and myrobalan plum. It is native to Southeast Europe and Western Asia, and is naturalised in the British Isles and scattered locations in North America. Also naturalized in parts of SE Australia where it is considered to be a mildly invasive weed of bushland near urban centers. P. cerasifera is believed to one of the parents of the Cultivated Plum, Prunus domestica perhaps crossing with the sloe, Prunus spinosa, or perhaps the sole parent. This would make it a parent of most of the commercial varieties of plum in the UK and mainland Europe - Victoria, greengages, bullace etc.
