Prunus avium, commonly called wild cherry, sweet cherry, gean, or bird cherry is a species of cherry, a flowering plant in the rose family, Rosaceae. It is native to Europe, Anatolia, Maghreb, and Western Asia, from the British Isles south to Morocco and Tunisia, north to the Trondheimsfjord region in Norway and east to the Caucasus and northern Iran, with a small isolated population in the western Himalaya. The species is widely cultivated in other regions and has become naturalized in North America and Australia.
Prunus avium has a diploid set of sixteen chromosomes (2n = 16). All parts of the plant except for the ripe fruit are slightly toxic, containing cyanogenic glycosides.
The early history of its classification is somewhat confused. In the first edition of Species Plantarum (1753), Linnaeus treated it as only a variety, Prunus cerasus var. avium, citing Gaspard Bauhin's Pinax theatri botanici (1596).
His description, Cerasus racemosa hortensis ("cherry with racemes, of gardens")[clarification needed shows it was described from a cultivated plant. Linnaeus then changed from a variety to a species Prunus avium in the second edition of his Flora Suecica in 1755.
Sweet cherry was known historically as gean or mazzard (also 'massard'). Until recently, both were largely obsolete names in modern English.
The name "wild cherry" is also commonly applied to other species of Prunus growing in their native habitats, particularly to the North American species Prunus serotina.
Prunus avium means "bird cherry" in the Latin language, but in English "bird cherry" refers to Prunus padus.
Prunus avium is a deciduous tree growing to 15-32 m (49-105 ft) tall, with a trunk up to 1.5 m (4.9 ft) in diameter. Young trees show strong apical dominance with a straight trunk and symmetrical conical crown, becoming rounded to irregular on old trees.
