Report an issue with this species
Juglans cinerea, commonly known as butternut or white walnut, is a large deciduous tree native to the eastern United States and southeast Canada. This hardy species produces edible nuts, but also produces juglone, an organic compound that can inhibit the growth of nearby plants. The species is currently considered endangered due to overharvesting, limited geographic range, and widespread damage from fungal canker disease.
