June in a Wyoming native garden
June is Wyoming's peak bloom month: 61 of the state's 87 native plants in this directory flower in June, more than in any other month.
16 start blooming in June, including Aspen fleabane, Black-eyed Susan and Colorado blue columbine. 21 finish in June, including American plum, Antelope bitterbrush and Bearberry, so this is the last chance to see them in flower.
53 of them grow in full or partial sun and 17 tolerate shade, so there are options for open beds and woodland edges alike. Sizes run from low plants like Arrowleaf balsamroot and Aspen fleabane to trees such as American plum and Bearberry. For wildlife, 47 support pollinators, 35 provide food or cover for birds and 18 are caterpillar host plants.
44 of the 61 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.
