A feathery leaved, perennial, aquatic
plant with stems that grow up to 2 m
in length. The tips of the stems
frequently protrude from the
water up to 30 cm. Seeds are
infertile in Australia due to only
female plants being recorded
here. However, Parrot Feather
reproduces by fragments breaking
from the parent plant and moved
by water currents. This species may
also occur in home aquaria and
ponds as the plant was once sold
as an attractive fish tank plant. This
aquatic plant is capable of totally
choking water ways, dangerously
excluding all other flora and
fauna.
