About

The pecan (Carya illinoinensis) is a species of hickory native to the Southern United States and northern Mexico in the region of the Mississippi River.

Originally native to the south-central U.S., the tree is cultivated for its seed primarily in the U.S. states of Georgia, New Mexico, Texas, Louisiana and in Mexico. The seed is an edible nut used as a snack and in various recipes, such as praline candy and pecan pie. The pecan is the state nut of Alabama, Arkansas, California, Texas, and Louisiana, and is also the state tree of Texas.

How to grow it

Pecans are one of the most recently domesticated of the major crops. Although wild pecans were well known among native and colonial Americans as a delicacy, the commercial growth of pecans in the United States did not begin until the 1880s. As of 2014, the United States produced an annual crop of 119.8 million kilograms (264.2 million pounds), with 75% of the total crop produced in Georgia, New Mexico, and Texas. They can be grown from USDA hardiness zones approximately 5 to 9, and grow best where summers are long, hot and humid. The nut harvest for growers is typically around mid-October.

The tree requires little pruning because it naturally forms a vase-shaped canopy; the only pruning necessary is to remove diseased, broken, or dead limbs.

Where it grows

Pecan trees are native to the south-central U.S., but have spread due to cultivation.

Uses

Pecan seeds are edible, with a rich, buttery flavor. They can be eaten fresh or roasted, or used in cooking, particularly in sweet desserts, such as pecan pie, a traditional Southern U.S. dish. Butter pecan is also a common flavor in cookies, cakes, and ice creams. Pecans are a significant ingredient in American praline candy. Other applications of cooking with pecans include pecan oil and pecan butter.
