Uses

Ethnobotanic: Woolgrass stems were woven to make matting and ropes. The fruiting tops of the plant were used as a resilient material for stuffing and making pillows (Moerman 1998). The small rushes were used in making woven mats and storage bags (Ibid.).

Status

Description

General: Sedge family (Cyperaceae). Woolgrass (Scirpus cyperinus) is a tall perennial with slender culms. This species is an erect grasslike plant that commonly grows four to five feet (Tiner 1987). The leaves are smooth, flat, elongated, and up to ½ inch wide. The flowers occur in dense rounded clusters of greenish-brown spiklets arising from the top of the culm. The fruits are yellow-gray to white achenes surpassed by long red-brown bristles at maturity. Distribution: Scirpus cyperinus ranges from New England and New York westward across Ohio to Iowa, and southward to North Carolina and Oklahoma. It is also found from Newfoundland to Minnesota south to Florida and Louisiana (Tiner 1987). For current distribution, please consult the Plant profile page for this species on the PLANTS Web site.

Adaptation

Woolgrass is found in irregularly flooded tidal fresh marshes, inland marshes, wet meadows, and swamps. This species grows best in areas with wet soil moisture content and is seldom found in more than a few inches of water (Voss 1972). It prefers peat or sandy soil types in full to partially sunny locations. R. Mohlenbrock USDA, NRCS, Wetlands Institute @ PLANTS

Establishment

Propagation by Seed: Scirpus cyperinus seeds should be sown in a cold frame as soon as they are ripe in a pot standing in three centimeters of water. The seeds germinate quickly. When they are large enough to handle, plant them into their permanent positions in early summer. Large divisions can be planted directly into their permanent positions. It is best to pot smaller divisions and grow them in a cold frame, out-planting when they are well established in the summer.

Management

After seed planting, water level over Scirpus cyperinus seeds should be maintained at one foot for two weeks. Periodic flooding up to three feet should occur until the seeds are established. Cultivars, Improved and Selected Materials (and area of origin) Available through wetland plant nurseries. Contact your local Natural Resources Conservation Service office for more information. Look in the phone book under ”United States Government.” The Natural Resources Conservation Service will be listed under the subheading “Department of Agriculture.”
