Present throughout the western part of Canada, Alaska, the western and southern part of the United States and a few, isolated eastern states, this plant is a Hydrophyte that is nearly always a wetland plant.
It commonly grows at low elevations in wet woods, sloughs, roadside ditches, brackish and freshwater marshes, around ponds and lakes and along streams. It rises in shallow water one to two and a half feet deep on sandy flats and beach pools.
This plant grows in water or moist soil where the minimum yearly water levels are not less than four to five inches above the soil surface.
