June in a Pennsylvania native garden
June is one of Pennsylvania's busiest bloom months, with 174 of the state's 308 native plants flowering (the peak is May).
44 start blooming in June, including American bellflower, Arctic brome (Kalm's brome) and Black-eyed Susan. 77 finish in June, including Allegheny chinquapin, Allegheny serviceberry and American bittersweet, so this is the last chance to see them in flower.
109 of them grow in full or partial sun and 120 tolerate shade, so there are options for open beds and woodland edges alike. Sizes run from low plants like American alumroot and Birdfoot violet to trees such as Allegheny chinquapin and Allegheny serviceberry. For wildlife, 138 support pollinators, 104 provide food or cover for birds and 64 are caterpillar host plants.
132 of the 174 have a seed or plant listing we verified as the wild species. Be careful buying American alumroot, Black-eyed Susan, Bog rosemary: 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.
