Prunus cerasifera is a species of plum known by the common names cherry plum and myrobalan plum. It is native to the British Isles, Southeast Europe and Western Asia and naturalized in scattered locations in North America.
Wild types are large shrubs or small trees reaching 8–(12) m (25–40 feet) tall, sometimes spiny, with glabrous, ovate deciduous leaves 3–7 cm (1.5–2.5 inches) long. It is one of the first European trees to flower in spring, often starting in mid-February before the leaves have opened. The flowers are white or pale pink and about 2 cm (0.8 inches) across, with five petals and many stamens. 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. The plant propagates by seed or by suckering, and is often used as the rootstock for other Prunus species and cultivars.
The cherry plum is a popular ornamental tree for garden and landscaping use, grown for its very early flowering. Numerous cultivars have been developed, many of them selected for purple foliage, such as P. pissardii (Carrière) L.H. Bailey (P. 'Atropurpurea'). The variety 'Nigra' with black foliage and pink flowers, has gained the Royal Horticultural Society's Award of Garden Merit. These purple-foliage forms (often called 'purple-leaf plum'), also have dark purple fruit, which make an attractive, intensely coloured jam. They can have white or pink flowers. The cultivar 'Thundercloud' has bright red foliage which darkens purple. Others, such as 'Lindsayae', have green foliage. Some kinds of purple-leaf plums are used for bonsai and other forms of living sculpture.
