There are over 500 different types of pecans. Many of them are named after Native American tribes, while others are named after the person who originally grafted the pecan plant. Different types of pecans are often distinguished by the size and flavor of the nut.
It is often difficult to distinguish between different varieties of pecan. The trees appear quite similar to one another. Along with the size and flavor of the nut, shell thickness can be used as a way to distinguish one pecan from another. Thinner-shelled pecans are often more desirable as they are easier to crack. Some popular types of pecans are Stuart, Desirable, Moreland and Cape Fear.
