About Stone Fruits
Peaches, plums, and nectarines were first cultivated in ancient China. They are members of the genus Prunus, which also includes other stone fruits like cherries, almonds, and apricots.
The Peach
The earliest mentions of peaches in Chinese literature date to 1000 B.C.E., when a book of poems and songs was written describing pink peach blossoms and peach trees with ripe fruit. The fruit spread westward to Persia and Rome via caravan trade on the Silk Road in the second century B.C.E., and from Rome, throughout Europe.
Peaches were introduced to the United States by the Spanish in Florida during the 1500s. From there, they spread up the East Coast and west to the Mississippi. Several groups brought peaches to California. Spanish missionaries were first in the 1700s. In the early 1800s, Russian immigrants brought peach seeds or trees by ship to San Francisco, and during the Gold Rush, settlers in California planted peaches as well.
The Nectarine
Nectarines also originated in China, and likely arose from natural variation in peach seeds. Peach trees will sometimes produce a few nectarines, and nectarine trees a few peaches. They’re close relatives; in fact, they’re only one gene different – the one that controls the fuzz. Nectarines have gotten their own name relatively recently; they were described historically as "fuzzless peaches."
The Plum
Though plums arose in China, most of the plums sold in the U.S. and Canada are known as Japanese plums. These plums are rounded in shape, with some having a small pointed tip. The first Japanese plums came to California from Japan in 1870.
European plums are the other type of plums available from California. These plums are oval or teardrop-shaped, have purple to blue skin and are smaller than Japanese plums. Early settlers brought this plum to the United States.
In California
California produces 76% of U.S. peaches and 93% of U.S. nectarines and plums. About 90% of California peaches, plums and nectarines are grown in Fresno, Tulare, and Kern counties, in the heart of California’s central San Joaquin Valley. Other Central Valley counties and southern desert areas make up the rest of California’s 100,000 acres of peach, plum and nectarine production. The 50 million boxes of peaches, plums and nectarines sold each year contribute more than $350 million to the state’s agricultural economy.
