Kentucky coffeetree

Gymnocladus dioicus 路 Fabaceae 路 also Coffeetree

A large, open tree with a coarse, picturesque winter silhouette, deeply fissured scaly bark and huge doubly compound leaves up to 3 ft long that emerge pink-bronze and turn yellow in fall. It leafs out late and drops early. Female trees carry leathery brown pods all winter; podless male cultivars ('Espresso', 'Prairie Titan') avoid the litter. It tolerates heat, drought, salt, pollution and ice, making it one of the most dependable city trees.
