Prunus persica

The peach is a tree, Prunus persica, and the juicy fruit that it bears, which has a single large seed encased in hard wood (called the pit or stone), yellow or whitish flesh, a delicate aroma, and a velvety skin. Peaches, along with cherries, plums, and apricots, are stone fruits. Cultivated peaches are divided into freestone and clingstone varieties, depending on whether the flesh sticks to the pit; both kinds can be any color. Peaches with white flesh typically are very sweet with little acid flavor, while yellow-fleshed peaches typically have an acidic tang coupled with sweetness. Both colors often have some red on their skin. Low-acid white-fleshed peaches are the most popular kinds in China, Japan, and neighboring Asian countries, while Europeans and North Americans have historically favored the acidic, yellow-fleshed kinds.

The nectarine is a kind of peach that has a fuzzless, shiny skin. Though grocers treat fuzzy peaches and nectarines as different fruits, they belong to the same species. Nectarines have arisen many times from fuzzy peaches, often as bud sports. Nectarines can be white, yellow, clingstone, or freestone. Regular peach trees occasionally produce a few nectarines, and vice versa. Nectarines are more easily damaged than fuzzy peaches.

Culture

Peach trees grow well in a fairly limited range, since they have a chilling requirement that subtropical areas cannot satisfy, and they are not very hardy. A lot of summer heat is required to mature the crop. Important peach-producing areas are California, the countries surrounding the Mediterranean, South Carolina, Georgia and neighboring US states, and parts of China.

Most peach trees sold by nurseries are grafted cultivars. The trees are prone to a disease called leaf curl, which usually does not affect the fruit crop, merely the aesthetics of the tree, and the fruit is very susceptible to brown rot.
