April in an Iowa native garden
April is one of Iowa's busiest bloom months, with 91 of the state's 196 native plants flowering (the peak is May).
46 start blooming in April, including American basswood, American bladdernut and American hazelnut. 5 finish in April, including American sycamore, Bloodroot and Eastern cottonwood, so this is the last chance to see them in flower.
67 of them grow in full or partial sun and 62 tolerate shade, so there are options for open beds and woodland edges alike. Sizes run from low plants like Birdfoot violet and Bloodroot to trees such as American basswood and American bladdernut. For wildlife, 68 support pollinators, 59 provide food or cover for birds and 40 are caterpillar host plants.
83 of the 91 have a seed or plant listing we verified as the wild species. Be careful buying Common yarrow, Eastern hop-hornbeam, Sundial lupine: 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.
