English Walnuts


Overview


Two major varieties of walnuts are grown in the United States—the English walnut and the black walnut. The English walnut originated in Persia (now Iran). Commercially produced varieties are nearly all hybrids of the English walnut. The Northern California black walnut is primarily used as the rootstock for English walnut cultivars.

California produces 99 percent of the nation’s commercial English walnuts with almost all production taking place in the Sacramento and San Joaquin valleys.  March 2013 ...  English Walnuts
