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, cylindrical nuts inside sticky green hulls that earned it the nickname lemon-nut (Rink, 1990). The nuts, a preferred food of squirrels and other wildlife, 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 heartwood (Kellogg, 1919), and as a source of medicine (Johnson, 1884; Lawrence, 1998), dyes (Hamel and Chiltoskey, 1975), and sap sugar.
