Butternut, a Common Tree in North America

Butternut (Juglans cinerea), also called white walnut or oilnut, grows rapidly on well-drained soils of hillsides and streambanks in mixed hardwood forests. This small to medium-sized tree is short lived, seldom reaching the age of 75. Butternut is more valued for its nuts than for lumber. The soft coarse-grained wood works, stains, and finishes well. Small amounts are used for cabinetwork, furniture, and novelties. The sweet nuts are prized as a food by man and animals. Butternut is easily grown but must be transplanted early because of the quickly developing root system.

Cultivars of this species have been selected for nut size and for ease of cracking and extracting kernels. Nuts are especially popular in New England for making maple-butternut candy. Small amounts of wood are used for cabinets, toys, and novelties. Butternut is under attack by the butternut canker disease within its range.

The Range of Butternut

Butternut is found from southeastern New Brunswick throughout the New England States except for northwest Maine and Cape Cod. The range extends south to include northern New Jersey, western Maryland, Virginia, North Carolina, northwestern South Carolina, northern Georgia, northern Alabama, northern Mississippi, and Arkansas. Westward it is found to central Iowa and central Minnesota. It grows in Wisconsin, Michigan, and northeast into Ontario and Quebec. Through most of its range butternut is not a common tree, and its frequency is declining. The ranges of butternut and black walnut (Juglans nigra) overlap, but butternut occurs farther north and not as far south as black walnut.
