Wild types of Prunus cerasifera 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.
