Native to South America, this plant was introduced by the aquarium industry. It has a delicate appearance with leaves resembling fans, hence the nickname “fanwort”. It has a small flower held above the water; ranging in color from pink to yellow-white. Plant color varies widely, from green leaves to reddish.
Plants will grow in depths of twelve feet provided sunlight is strong enough. Reproduction occurs from fragmentation and rhizomes, allowing for rapid spreading which forces out other desirable species. Waterways are choked out once this plant is present.
Control with aquatic herbicides produces good results.
