Walnuts - The Royal Nut

Walnuts, the oldest tree food known to man are believed to have come from ancient Persia and were traded between Asia, the Middle East, and far off lands, making the Walnut one of the most popular nuts in the world.

Today, California Walnut Handlers continue to be very successful with the sales and marketing of the English Walnut. The California Nut Trade continues to process and produce the Top Quality Walnut for the world.

Harvesting begins in late August and continues until late November of each year. Each year many varieties of walnuts are grown in California. Only six account for over 75 percent of the total production: Hartley, Chandler, Serr, Vina, Franquette and Howard.
