Where it grows wild

Wet ground in full sun: marshes, pond and stream margins, ditches and rice paddies, often with Polygonum and Cyperus. Aerenchyma tissue lets it cope with waterlogged, oxygen-poor mud.

Recorded from sea level to about 2,760 m, with a median of 100 m. It is mainly a lowland plant.
