Wapato is a colony-forming, aquatic perennial typically found in swamps and ponds. It flaunts showy white and yellow flowers in mid-late summer on stalks up to 3' high. In mud, the rhizomes produce starchy tubers that are an important food source and culturally significant for Native Americans. It is also utilized by 15 different waterbirds and muskrats, which is how it gets a well-earned nickname "duck potatoes".
