The earliest California walnuts were known as "mission" walnuts, named for the Franciscan Fathers who cultivated them in the late 1700s. By the 1870s, modern walnut production had begun in Southern California near Santa Barbara. Over the next 70 years much of the state's walnut production was moved to the central and northern parts of California.
Today almost all California walnuts come from the Central Valley, the state's primary growing region. The region's mild climate and deep fertile soils provide ideal growing conditions for California walnuts. The California walnut trade continues to be a well established, ordered, and structured business, making the California walnut the highest quality walnut available in the world.
