April in a Delaware native garden
April is one of Delaware's busiest bloom months, with 134 of the state's 255 native plants flowering (the peak is May).
59 start blooming in April, including Adam's needle, American basswood and American beech. 11 finish in April, including American elm, American sycamore and Black ash, so this is the last chance to see them in flower.
88 of them grow in full or partial sun and 90 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, 101 support pollinators, 91 provide food or cover for birds and 64 are caterpillar host plants.
106 of the 134 have a seed or plant listing we verified as the wild species. Be careful buying American alumroot, Common yarrow, Creeping phlox: 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.
