June in a Montana native garden
June is Montana's peak bloom month: 56 of the state's 78 native plants in this directory flower in June, more than in any other month.
15 start blooming in June, including Black-eyed Susan, Colorado blue columbine and Fireweed. 17 finish in June, including American plum, Antelope bitterbrush and Bearberry, so this is the last chance to see them in flower.
51 of them grow in full or partial sun and 14 tolerate shade, so there are options for open beds and woodland edges alike. Sizes run from low plants like Arrowleaf balsamroot and Black-eyed Susan to trees such as American plum and Bearberry. For wildlife, 45 support pollinators, 34 provide food or cover for birds and 16 are caterpillar host plants.
39 of the 56 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.
