May in a Tennessee native garden
May is Tennessee's peak bloom month: 202 of the state's 319 native plants in this directory flower in May, more than in any other month.
49 start blooming in May, including American beautyberry, American bittersweet and American cranberry. 64 finish in May, including American beech, American hornbeam and Appalachian gooseberry, so this is the last chance to see them in flower.
118 of them grow in full or partial sun and 142 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, 149 support pollinators, 122 provide food or cover for birds and 65 are caterpillar host plants.
154 of the 202 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.
