Description

Typically it forms a large shrub or a small tree. It may be somewhat thorny, with white blossom, borne in early spring. The oval or spherical fruit varies in size, but can be up to across. The pulp is usually sweet, but some varieties are sour. Like all ''Prunus'' fruits, it contains a single large seed, usually called a stone, which is discarded when eating.

Taxonomy

Subspecies

Cullen ''et al.'' (1995) recognises three subspecies, though scientific studies favor a more fine-grained separation: The subspecies cross easily, so that numerous intermediate forms can be found: their sweetness and tartness may vary, their colors varying from bluish-purple to red, orange, yellow or light green.
