September in a South Carolina native garden
September is a quieter month in South Carolina: 71 of the state's 292 native plants flower in September, compared with 191 at the May peak. That makes these plants valuable for keeping color, and food for pollinators, going outside the main season.
Witch-hazel starts blooming in September. 33 finish in September, including Blue vervain, Butterflyweed and Common buttonbush, so this is the last chance to see them in flower.
56 of them grow in full or partial sun and 24 tolerate shade, so there are options for open beds and woodland edges alike. Sizes run from low plants like Black-eyed Susan and Butterflyweed to trees such as Carolina jessamine and Devil's walking stick. For wildlife, 59 support pollinators, 46 provide food or cover for birds and 20 are caterpillar host plants.
60 of the 71 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.
