Bailey lists 82 species of Prunus, mostly native to the north temperate zone, and most of which produce edible fruits. Most Prunus species are small trees or shrubs, but some, as sweet cherries, become large trees. Fruits are characterized by a single stone or pit, surrounded by fleshy edible tissue which adheres to the skin. Trees shed their leaves in late fall, and most kinds require some exposure to cold weather for substantial fruiting. Kinds grown commercially for their fruit include apricots, sweet and sour cherries, peaches and nectarines, plums and prunes. Fruit of some species, not cultivated, may be gathered from the wild. In addition to production for fruit, many kinds of Prunus are grown as ornamentals.
