Notes
Gently flowing clean cold water. This plant was popular many years ago but today is listed as a Class B noxious weed. It has a delicate fern-like appearance with branches up to 1.5m. It is more suited to cold water but can be used to advantage to decorate a tropical tank. It is a true floating plant and does not take root.
Propagation
Grows readily from stem cuttings
