The plant is easily identifiable by its dense brown, cylindrical spikes that can resemble a cat’s tail. The plants growth can be described as very vigorous in wet areas.
It commonly grows along edges of water bodies in slow-moving water.
It reproduces vegetatively via underground stems whose buds develop new roots and shoots. It also reproduces by seeds.
Pollen requires strong winds for dispersal. The plant spreads through underground stems (rhizomes) and seeds are spread in water.
It can help stabilise banks and prevent erosion.
