American Bladdernut is a native shrub or small tree of moist, rich forests with distinctive inflated papery seed capsules that rattle in autumn wind, giving it its name. It grows along stream banks and moist slopes and produces small white bell-shaped flowers in May. Native bees are important pollinators, and the seeds are edible.
