The hickory trees are an important group within the Eastern hardwood forests. Botanically they are split into two groups: The true hickories, and the pecan hickories (fruit bearing). The wood is virtually the same for both and is usually sold together. Hickory is the hardest, heaviest and strongest American wood. The sapwood of hickory is white, tinged with inconspicuous fine brown lines while the heartwood is pale to reddish brown. Both are coarse-textured and the grain is fine, usually straight but can be wavy or irregular.
