Wikipedia Abstract

Carya tomentosa, (mockernut hickory, mockernut, white hickory, whiteheart hickory, hognut, bullnut) is a tree in the Juglandaceae or walnut family. The most abundant of the hickories, common in the eastern half of the US, it is long lived, sometimes reaching the age of 500 years. A straight-growing hickory, a high percentage of its wood is used for products where strength, hardness, and flexibility are needed. The wood makes an excellent fuelwood, as well.
