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.

A naturalized population of Prunus angustifolia in Santa Barbara County, California, has been extirpated.

Prunus angustifolia is one of the more distinctive plum species in North America. The leaves are relatively small, usually folded along their midribs, and have relatively large, reddish orange, conic glands along the margins. When it hybridizes with other plums, the hybrids often have distinctive characteristics and have been named as species more often than hybrids not involving P. angustifolia: P. ×orthosepala Koehne (angustifolia × americana), P. ×slavinii E. J. Palmer ex Rehder (angustifolia × gracilis), P. ×utahensis Koehne (angustifolia × pumila var. besseyi); see also discussion under 42. P. rivularis.
