Field Notes

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

Habitat:

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.
