Discussion

Peaches are cultivated throughout much of North America. Commercial production is diffuse, occurring in over half of the lower 48 states as well as in southern British Columbia and southern Ontario. Freestone peaches for fresh eating come largely from California, Georgia, New Jersey, North Carolina, Pennsylvania, and South Carolina; most clingstones are used for canning and are grown in California. Nectarines are a variety with hairless skin. The fruits are popular on picnics, and peach saplings are commonly encountered anywhere pits are discarded. Escapes are usually short-lived; some escapes form naturalized populations. Double-flowered cultivars are used ornamentally.

The distinctions given in the literature between Prunus domestica and P. insititia, and which cultivated varieties are derived from each of them, are contradictory and confusing. After examining plants from North America, it seems best to treat these Eurasian introductions as one variable species without designation of infraspecific taxa.

European plums are grown along the West Coast, primarily in California, for prunes and other processed food. They are also grown in the Great Lakes region of Ontario, Michigan, and New York for both prunes and the local fresh market. Most of the commercial fresh plum market is supplied by fruits of the Japanese plum, Prunus salicina, and its hybrid derivatives, which include genetic material from native American species, for example, P. americana, P. angustifolia, and P. hortulana.
