What is a walnut?

Walnuts are round, single-seeded stone fruits. Walnuts are late to grow leaves, typically not until more than halfway through the spring. Following full ripening, the removal of the husk reveals the wrinkly walnut shell, which is usually commercially found in two segments. The two most common major varieties of walnuts are grown for their seeds – in California, currently, our predominant walnut varieties are Chander and Howard due to their high quality and color.


Who grows walnuts?

As of 2019, world production of walnuts (in shell) was 4.5 million tons , with China contributing 56% of the total. Other major producers were the United States, Iran, and Turkey. Almost all the walnuts produced in the United States are produced in California, although a small proportion of walnuts are also grown in the Midwest. Here in California, our walnut harvests are pushing towards 350,000 acres of walnut trees cultivated for food.
