Another marsh plant seen at Lake Waban in Wellesley, MA. Grows with its feet in water, can be one to three feet tall with big arrow-shaped leaves. Very attractive to insects because it has 25-40 stamen and can hold loads of pollen. Ducks feed on the tubers and seeds. Muskrats eat them too. Native. Water Plantain family.
