October in a New Hampshire native garden
October is a quieter month in New Hampshire: 13 of the state's 141 native plants flower in October, compared with 88 at the May peak. That makes these plants valuable for keeping color, and food for pollinators, going outside the main season.
9 finish in October, including Black-eyed Susan, Cardinal flower and Cutleaf coneflower, so this is the last chance to see them in flower.
9 of them grow in full or partial sun and 8 tolerate shade, so there are options for open beds and woodland edges alike. Sizes run from low plants like Black-eyed Susan and Partridgeberry to trees such as Balsam fir and Witch-hazel. For wildlife, 8 support pollinators, 9 provide food or cover for birds and 3 are caterpillar host plants.
All 13 have a seed or plant listing we verified as the wild species. Be careful buying Black-eyed Susan: common listings for it are often a bred variety or a different species.
Good places to start
