Black walnut (Juglans nigra) is also known as American walnut. The tree is one of the most sought after of the native hardwoods. The tree grows in small natural groves. They are frequently found in mixed forests. They thrive well on moist alluvial soils. The tree has been heavily logged for its fine straight-grained wood that was used to make furniture and gunstocks. With the decreasing resource, the wood is used primarely for veneer. The nuts from black walnuts have been for food and medicine for a long time. The bark of the tree and shell of the nuts are also used for many purposes.
