Origin
Native to Asia.

Appearance
Emergent, perennial, aquatic plant arising from rhizomes (underground stems) buried in the underwater substrate. The plant consists of a flowering stalk and 4 or more leaves. Grows approx. 1-2 m tall (approx. 3-7′).

Foliage
Leaves attach to rhizomes underwater. They are linear with pointed tips, smooth, green, stiff and may be slightly twisted; 0.5-1 cm wide (up to approx. 0.5″) and approx. 0.5-2 m long (approx. 1.5-6′).

Flowers
The flowering stalk is light green, smooth, stiff, round in cross-section and about as long as the leaves. Male and female flowers are densely packed in clusters around the end of the same flower stalk; male flowers are above and separated from the female flowers by a 0.5-12 cm gap (up to 4″). Male flowers disappear after shedding pollen.

Fruit
Female flowers develop into tiny seeds with light, soft, fluffy, hair-like attachments.

Ecological Threat
May form dense monocultures. The dense rhizome mats may close open water areas and compete with native wetland plants.
