About Bladdernut, American
Understory tree with downward-facing clusters of bell-shaped white flowers in mid-May, giving way to papery, inflated 2" brown seed pods. In fall, the ripened seeds inside the pods rattle in the wind. Pods persist into winter and are good for dried flower arrangements. Seeds can be collected in fall and eaten raw or cooked.
