Dry savanna (especially oak) and thickets; shores, prairies.
A handsome species, with rich-colored flowers. The leaves tend to be more acute than in A. syriaca and usually somewhat less prominently pinnate-veined (the net-venation more evident). The leaves of A. syriaca are very prominently pinnate-veined and usually ± obtuse, but the two species are sometimes difficult to distinguish. An old collection from St. Clair Co. looks suspiciously like a hybrid with A. syriaca, and others from Jackson Co. also may show some influence of that species.
