Pecan vs. Walnut — What's the Difference?

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. The tree is cultivated for its seed in the southern United States, primarily in Georgia, New Mexico, and Texas, and in Mexico, which produces nearly half of the world total.
