Butternut

Arbor Walk #161

Although this tree has a broad range within the Upper Midwest and Northeast United States, it is uncommon in most of its range, being overshadowed by its ubiquitous relative Juglans nigra, the black walnut. Its lack of prominence is mainly caused by the deadly butternut canker, which only affects J. cinerea.

This tree has namesake edible nuts, pinnately compound leaves, an upright form, and medium height (40-60 feet tall). It also has lighter bark than the black walnut, inspiring the other common name, white walnut.
