March in a New Hampshire native garden
March is a quieter month in New Hampshire: 40 of the state's 141 native plants flower in March, compared with 88 at the May peak. That makes these plants valuable for keeping color, and food for pollinators, going outside the main season.
34 start blooming in March, including American holly, American hornbeam and Atlantic white cedar.
29 of them grow in full or partial sun and 27 tolerate shade, so there are options for open beds and woodland edges alike. Sizes run from low plants like Birdfoot violet and Carolina springbeauty to trees such as American elm and American holly. For wildlife, 29 support pollinators, 29 provide food or cover for birds and 23 are caterpillar host plants.
33 of the 40 have a seed or plant listing we verified as the wild species. Be careful buying Creeping phlox, Pitch pine, Wild blue phlox: 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.
