The pecan is the edible seed of the hickory tree *Carya illinoinensis*, native to temperate North America. It is widely used in baking and desserts, such as pecan pie, and is sold in Canada as a snack and ingredient.

What it is

The pecan (*Carya illinoinensis*) is a species of hickory in the walnut family (Juglandaceae). Its smooth, thin-shelled nut is commonly eaten raw, salted, or sweetened. Botanically, it is a drupe-like fruit, but it is referred to as a nut.

Where it grows and how it's used

Pecans are native to river-basin regions of the central and southern United States and northern Mexico. They are now commercially cultivated in warm areas, with major production in the US. In Canada, pecans are imported and used in holiday baking, desserts, and as a snack.

Nutritional and cultural significance

Pecans have a high fat content, much of it unsaturated, making them calorie-dense. They are a key ingredient in pecan pie and pralines. The pecan tree is the state tree of Texas, reflecting its cultural importance in the American South.
