A. A. Reznicek
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. This has unique leaves, the largest of any native tree, twice-pinnate with entire leaflets, approaching a meter long in vigorous sprouts. The heavy, woody, large-seeded pods, as much as 20 cm long and 5 cm wide, remain on the tree until early spring.
