Impacts of this species 

Fanwort can form dense populations that interfere with recreation and clog drainage systems. It can grow from plant fragments, making it easier to spread.


Fanwort is native to North America but invasive in New England. It is sold as an aquarium plant and is often introduced from aquarium dumping.
