June in a Delaware native garden
June is one of Delaware's busiest bloom months, with 141 of the state's 255 native plants flowering (the peak is May).
35 start blooming in June, including Black-eyed Susan, Blue vervain and Brown-eyed Susan. 59 finish in June, including Allegheny chinquapin, Allegheny serviceberry and American bittersweet, so this is the last chance to see them in flower.
91 of them grow in full or partial sun and 94 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, 118 support pollinators, 93 provide food or cover for birds and 61 are caterpillar host plants.
115 of the 141 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.
