Bitternut hickory is a large north American native tree, best reserved for larger landscapes. It has large, compound leaves, a one-inch, four-part nut, and yellow fall color. Like all hickories, debris from its fruit drops from late summer throughout autumn, making fall cleanup in urban areas more challenging.
This species is native to the Chicago region according to Swink and Wilhelm's Plants of the Chicago Region, with updates made according to current research.
