Rotala rotundifolia
Also called Dwarf Rotala
Roundleaf toothcup is a small aquatic or wetland plant, widely sold for aquariums and common as a weed in rice paddies. It grows well submerged or emersed in shallow water and needs good light to stay compact and colorful.
Rotala rotundifolia, the dwarf rotala, is a plant species often confused with Rotala indica. It is sold in the aquarium trade, but is of uncertain status.
It is a common weed in rice paddies and wet places in India, China, Taiwan, Thailand, Laos, and Vietnam, and has been introduced to the United States.
A common aquarium plant, it is undemanding, but requires light to thrive. R. rotundifolia can withstand relatively cool temperatures. Losing its lower leaves usually means it is not receiving enough light. It can be grown emersed in shallow water, where it will flower. It is propagated by cuttings.
