July in a Delaware native garden
July is a quieter month in Delaware: 101 of the state's 255 native plants flower in July, compared with 151 at the May peak. That makes these plants valuable for keeping color, and food for pollinators, going outside the main season.
21 start blooming in July, including Blue mistflower, Coastal sweetpepperbush and Common evening primrose. 29 finish in July, including American basswood, American cranberry and Black huckleberry, so this is the last chance to see them in flower.
72 of them grow in full or partial sun and 58 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 American basswood and Black willow. For wildlife, 89 support pollinators, 65 provide food or cover for birds and 38 are caterpillar host plants.
83 of the 101 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.
