Broadleaf Arrowhead is a distinctive native aquatic and emergent wetland plant with large, arrowhead-shaped leaves and whorled spikes of white, three-petaled flowers. Found in shallow water and muddy shores across most of North America, it produces starchy underground tubers called 'duck potatoes' that were a major food source for Indigenous peoples and are eagerly consumed by ducks and geese. The tubers were called wapato and were an important trade item among Pacific Northwest tribes.
