About Hygrophila costata Nees
Hygrophila costata, with common names glush weed, gulf swampweed, and yerba de hicotea, is an aquatic plant. It is native to Neotropic ecoregions, including Florida, the Caribbean, southern Mexico, Central America, and South America. It is recorded in Carl Friedrich Philipp von Martius' Flora Brasiliensis, and occurs in the Cerrado ecoregion of Brazil. Because it is commonly kept as a freshwater aquarium plant, Hygrophila costata has become an invasive, dominant species in several parts of the world, including Australia.
