The pecan (Carya illinoinensis) are the fruit of a kind of hickory tree, native to North America and Mexico. Pecans were one of the most recently domesticated major crops. Although wild pecans were well known among native and colonial Americans as a delicacy, the commercial growing of pecans in the United States did not begin until the 1880s. Today, the U.S. produces between 80% and 95% of the world's pecans, with an annual crop of 150–200 thousand tons.
