About
Brazilian Waterweed
Brazilian waterweed is a submersed, perennial, freshwater herb. It grows from erect, cylindrical stems until it reaches the surface of the water, where it then forms dense mats. While very pervasive in neighboring states, Brazilian waterweed is not yet very prominent in Wisconsin. It was introduced worldwide through the aquarium trade.
