Shagbark hickory

Plant a shagbark hickory in a large landscape for excellent shade. This Midwest native is named for its bark, which peels away in large, flat, curving plates, giving the tree a shaggy appearance. As a member of the walnut family, the hickory produces edible nuts.

"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."
