Gymnocladus dioicus leaves A. A. Reznicek leaves

Rich mesic and floodplain forests. Native as far north as southern Michigan. Sometimes also planted as a shade tree, but, unlike Gleditsia, does not spread so readily.

The heavy, woody, large-seeded pods, as much as 15 cm long and 4 cm wide, remain on the tree until early spring.
