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.
