August in a Louisiana native garden
August is a quieter month in Louisiana: 54 of the state's 179 native plants flower in August, compared with 121 at the May peak. That makes these plants valuable for keeping color, and food for pollinators, going outside the main season.
8 start blooming in August, including Big bluestem, Dotted blazing star and Indiangrass. 10 finish in August, including American bellflower, Golden alexanders and Indian blanket, so this is the last chance to see them in flower.
45 of them grow in full or partial sun and 15 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, 49 support pollinators, 34 provide food or cover for birds and 19 are caterpillar host plants.
47 of the 54 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.
