Genus:Juglans

Species:cinerea

Family:Juglandaceae

Butternut is a sizable shade tree belonging to the walnut family, found primarily in the moist bottomlands, lowland forests, and some drier limestone areas of eastern and midwestern North America. While the shells of its nuts can be challenging to crack, the nuts themselves are sweet and oily, making them highly sought after by both humans and wildlife.

For optimal growth, plant butternut in well-drained, moist soil with full sunlight, as it does not thrive in shaded areas or in competition with other plants. Once established, these trees can withstand drought conditions and are resilient against browsing by rabbits. Similar to black walnut trees, butternuts release juglones, which are harmful to surrounding vegetation, with the impact typically reaching the tree's drip line.

Unfortunately, butternut trees are currently endangered in their native habitats due to the spread of butternut canker disease and excessive harvesting. This disease has severely affected the species, and there is no known cure. Although butternuts are not commonly used for ornamental purposes, their status as a native tree makes them a species worth preserving.

Juglans cinerea Feature Summary

Attributes
Used to make furniture, cabinetry, instrument cases, interior woodworks, hand-carved wall panels, trim, church decoration and altars. Nut popularly used in New England for making maple-butternut candy. Early settlers used fruit husks and inner bark to make orange or yellow dye and the root bark for a laxative. Native Americans used the nuts for food and boiled the tree sap for syrup.
Canada, central and eastern U.S.A., NC
Found from Quebec south throughout the New England states to GA west to MS and AR north through Manitoba
Provides food for squirrels and other rodents, birds and mammals. This plant supports Hickory Horndevil (Citheronia regalis) larvae which have one brood and appear from May to mid-September. Adult Hickory Horndevil moths do not feed. Larval host plant for the Luna moth.
Nuts are edible and sought after by food enthusiasts.
