Additional Information

The Pecan is a tall, straight-trunked tree and is the largest of the hickories. It is well-known for its sweet, edible nuts and because of this, it is an important horticultural crop in the south, where it produces fruit most abundantly. However, it is not generally recommended for use in the landscape, due to its pest susceptibility and litter problem. With its large taproot, it can also be quite difficult to transplant.
