Graceful Cattail
(Typha laxmannii)

Graceful cattail is a perennial wetland plant native to marshes and wetlands in Europe and Asia that spreads by creeping rhizomes to form dense colonies in shallow water. It grows 3-5 feet tall, often with a submerged base.



Overview

Regulated areas of Graceful Cattail
This species is Prohibited (Red counties)

Other names for this plant include:

  • Common names: Laxman’s bulrush
  • Scientific names: Typha stenophylla

Ecological threat:

  • Invades freshwater marshes, wet meadows, fens, roadsides, ditches, shallow ponds, stream, and lake shores.
  • Plays an important role as a source of food and shelter for some marsh-dwelling animals, but large mono-specific stands of invasive cattails exclude some less common species.

Classification in Wisconsin: Prohibited

Species Assessment Groups (SAG) were assembled to recommend a legal classification for each species considered for NR 40. The recommendation for graceful cattail was based upon this literature review developed by the department.

Identification

Leaves: Narrow green leaves grow linear and sword-like up to 5 feet tall.

Flowers: Yellowish male flowers are located at the top of a flower stalk and greenish female flowers are located up to 2 inches underneath.

Fruits & seeds: After pollination the female flowers turn brown similar to other cattail species as the seeds mature. The seeds are tiny (about 1 mm), dispersed by wind with the aid of numerous hairs.

Roots: Plants can spread vegetatively by means of starchy underground rhizomes to form large colonies.

Similar species: There are other species of cattail in Wisconsin that may be confused with graceful cattail. Broad leaved cattail (Typha latifolia) is native to WI, while narrow-leaved (T. angustifolia) and hybrids (T. glauca) are also considered invasive. Graceful cattail is smaller than the other species of cattail and its fruiting spike is smaller than other species (typically around 4 inches).

Control

Mechanical: Cut all stems, both green and dead in mid to late summer or early fall. Where possible maintain a water level of a minimum of 3” above the cut stems for the entire growing season.

Chemical: Foliar spray with aquatic approved imazypr. Herbicide applications near water may require a permit.
