May in a North Carolina native garden
May is North Carolina's peak bloom month: 205 of the state's 315 native plants in this directory flower in May, more than in any other month.
47 start blooming in May, including American beautyberry, American bittersweet and American cranberry. 66 finish in May, including American beech, American hornbeam and American olive, so this is the last chance to see them in flower.
120 of them grow in full or partial sun and 141 tolerate shade, so there are options for open beds and woodland edges alike. Sizes run from low plants like American alumroot and Birdfoot violet to trees such as Allegheny chinquapin and Allegheny serviceberry. For wildlife, 152 support pollinators, 121 provide food or cover for birds and 68 are caterpillar host plants.
154 of the 205 have a seed or plant listing we verified as the wild species. Be careful buying American alumroot, American wisteria, Common yarrow: 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.
