August in a New Jersey native garden
August is a quieter month in New Jersey: 91 of the state's 287 native plants flower in August, compared with 172 at the May peak. That makes these plants valuable for keeping color, and food for pollinators, going outside the main season.
14 start blooming in August, including Big bluestem, Closed bottle gentian and Groundsel tree. 27 finish in August, including Adam's needle, American alumroot and American bellflower, so this is the last chance to see them in flower.
68 of them grow in full or partial sun and 42 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 Great laurel and Smooth sumac. For wildlife, 79 support pollinators, 54 provide food or cover for birds and 29 are caterpillar host plants.
75 of the 91 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.
