Butternut

Juglans cinerea, commonly called the butternut or white walnut, is a species of walnut in the family Juglandaceae, native to the eastern United States and southeastern Canada, ranging from New Brunswick west through southern Quebec to Minnesota and south to northern Alabama and Arkansas, largely absent from the rest of the southern United States because it prefers cooler climates than its relative the black walnut. It is a deciduous tree that grows to about 30 meters but is slow growing, with a typical lifespan under 75 years. Its nuts are edible, and Native Americans historically processed butternuts into a butter-like oil; the young green nuts can be pickled while still soft, and the tree's sap can be tapped to make syrup. The species is currently listed as Endangered by the IUCN Red List due to significant population decline across its native range.
