Where it grows wild

It floats just below the surface in shallow, still or slow fresh water, in marshes (esteros), flooded savanna, morichal (palm-swamp) streams, coastal lagoons, flooded restinga and temporary pools between dunes. The water is usually soft and low in nutrients.

Records run from sea level to about 510 m, with most below 250 m.
