September in an Arkansas native garden
September is a quieter month in Arkansas: 77 of the state's 278 native plants flower in September, compared with 178 at the May peak. That makes these plants valuable for keeping color, and food for pollinators, going outside the main season.
2 start blooming in September, including White heath aster and Witch-hazel. 40 finish in September, including Blue vervain, Butterflyweed and Common buttonbush, so this is the last chance to see them in flower.
63 of them grow in full or partial sun and 25 tolerate shade, so there are options for open beds and woodland edges alike. Sizes run from low plants like Black-eyed Susan and Buffalograss to trees such as Carolina jessamine and Devil's walking stick. For wildlife, 67 support pollinators, 52 provide food or cover for birds and 25 are caterpillar host plants.
68 of the 77 have a seed or plant listing we verified as the wild species. Be careful buying Black-eyed Susan, Common yarrow, Crimson-eyed rose-mallow: common listings for these are often a bred variety or a different species.
Good places to start
Verified wild-species listings that take sun and are widely native, so they are forgiving first plants.
