Large deciduous tree useful for its high-quality lumber, and which also produces nuts edible by wildlife and humans. Nuts are surrounded by green or yellow-green husks that blacken on the ground during fall maturation. Compound leaves emit fragrance when crushed, emerging late and falling early; up to 2′ long, with many leaflets, generally lance-shaped, alternately arranged in a pattern broadly reminiscent of a feather. Produces compounds called juglones, which can harm some plants though many natives are not susceptible. Host to numerous larvae including the caterpillars of walnut datana moths, luna moths, and regal moths (aka hickory horned devil with its remarkable namesake horns).
