Description: Butternut (Juglans cinerea), also known as white walnut, is a native hardwood related to black walnut (Juglans nigra) and other members of the walnut family. Butternut is a medium-sized tree with alternate, pinnately compound leaves that bears large, sharply ridged and corrugated, elongated, cylindrical nuts born inside sticky green hulls that earned it the nickname lemon-nut (Rink, 1990). The nuts are a preferred food of squirrels and other wildlife. Butternuts were collected and eaten by Native Americans (Waugh, 1916; Hamel and Chiltoskey, 1975) and early settlers, who also valued butternut for its workable, medium brown-colored wood (Kellogg, 1919), and as a source of medicine (Johnson, 1884), dyes (Hamel and Chiltoskey, 1975), and sap sugar.
