August in a Tennessee native garden
August is a quieter month in Tennessee: 102 of the state's 319 native plants flower in August, compared with 202 at the May peak. That makes these plants valuable for keeping color, and food for pollinators, going outside the main season.
15 start blooming in August, including Big bluestem, Dotted blazing star and Groundsel tree. 28 finish in August, including Adam's needle, American alumroot and American bellflower, so this is the last chance to see them in flower.
75 of them grow in full or partial sun and 45 tolerate shade, so there are options for open beds and woodland edges alike. Sizes run from low plants like American alumroot and Black-eyed Susan to trees such as Carolina jessamine and Devil's walking stick. For wildlife, 90 support pollinators, 58 provide food or cover for birds and 30 are caterpillar host plants.
82 of the 102 have a seed or plant listing we verified as the wild species. Be careful buying American alumroot, Black-eyed Susan, Coastal sweetpepperbush: 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.
