June in a Maryland native garden
June is one of Maryland's busiest bloom months, with 180 of the state's 321 native plants flowering (the peak is May).
46 start blooming in June, including American bellflower, Arctic brome (Kalm's brome) and Black-eyed Susan. 80 finish in June, including Allegheny chinquapin, Allegheny serviceberry and American bittersweet, so this is the last chance to see them in flower.
113 of them grow in full or partial sun and 119 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, 146 support pollinators, 111 provide food or cover for birds and 66 are caterpillar host plants.
141 of the 180 have a seed or plant listing we verified as the wild species. Be careful buying American alumroot, American wisteria, Black-eyed Susan: 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.
