June in an Iowa native garden
June is one of Iowa's busiest bloom months, with 112 of the state's 196 native plants flowering (the peak is May).
28 start blooming in June, including American bellflower, Arctic brome (Kalm's brome) and Black-eyed Susan. 47 finish in June, including American bittersweet, American bladdernut and American hazelnut, so this is the last chance to see them in flower.
88 of them grow in full or partial sun and 61 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, 98 support pollinators, 67 provide food or cover for birds and 46 are caterpillar host plants.
101 of the 112 have a seed or plant listing we verified as the wild species. Be careful buying Black-eyed Susan, Common yarrow, Harebell: 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.
