June in a Connecticut native garden
June is one of Connecticut's busiest bloom months, with 94 of the state's 187 native plants flowering (the peak is May).
24 start blooming in June, including American bellflower, Black-eyed Susan and Blue vervain. 41 finish in June, including American bittersweet, American hazelnut and American holly, so this is the last chance to see them in flower.
63 of them grow in full or partial sun and 69 tolerate shade, so there are options for open beds and woodland edges alike. Sizes run from low plants like Birdfoot violet and Black-eyed Susan to trees such as American basswood and American bittersweet. For wildlife, 73 support pollinators, 63 provide food or cover for birds and 36 are caterpillar host plants.
72 of the 94 have a seed or plant listing we verified as the wild species. Be careful buying Black-eyed Susan, Bog rosemary, 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.
