A wetland plant that grows anywhere from North to South America. It has special stem tissue called aerenchyma used to carry oxygen to the roots of the plant since they have little access to oxygen in standing water. This plant is found in higher quality wetlands since it does not tolerate much disturbance and does not like the soil to dry out. It is found along the margins of ponds and lakes, swamps, bogs, and marshes. This plant can be confused with arrow arum and arrowhead when it is not in flower. It can be distinguished from the other two by having leaves that have a very fine venation pattern.
