The Pecan is native to northern Mexico and the southern United States, as it is primarily seen throughout Georgia, Texas, and Mexico. Texas has adopted this tree as their state tree. Mexico on the other hand is known to produce at least half of the world’s pecans. The seeds are edible nuts used in many snacks and recipes that we see today.
The pecan tree is a large deciduous tree, growing to 66 to 131 feet in height. It typically has a spread of 39 to 75 feet with a trunk up to 6 feet 7 inches diameter. A 10-year-old seedling grown in perfect conditions will stand about 16 feet tall.
A pecan is not truly a nut, but is technically a drupe, a fruit with a single stone or pit, surrounded by a husk. The husks are produced from the exocarp tissue of the flower, while the part known as the nut develops from the endocarp and contains the seed. The husk itself is a brassy greenish-gold in color, oval to oblong in shape. The outer husk starts out green and turns brown at maturity, at which time it splits off in four sections to release the thin-shelled seed.
