Scirpus cyperinus, commonly known as woolgrass, is an emergent wetland herb that is native to the eastern United States and eastern Canada. [2] Other common names include cottongrass bulrush [ 1 ] and brown woolly sedge .

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 1⁄2 inch wide. The flowers occur in dense rounded clusters of greenish-brown spiklets arising from the top of the culm.

Woolgrass Bulrush is a native aquatic sedge found in marshes, swamps, stream and/or pond margins, wet meadows other disturbed wet sites. It spreads by it creeping rhizomes in wet soils, including standing water. It prefers full sun but will appreciate some shade when grown in hot summer climates.

Scirpus cyperinus, commonly called woolgrass, is a grass-like, rhizomatous, emergent aquatic perennial of the sedge family that grows in dense slowly-spreading tussocks of arching basal green leaves with upright flowering stems (culms) rising to 3-5’ tall.

As the seed develops, it turns reddish brown and has a wool-like appearance that is very attractive from August through October. You can find Wool Grass all over the Eastern United States. Use this sedge in a rain garden or to spruce up the edge of a pond or stream bank. This map shows the native and introduced (adventive) range of this species.

Common woolsedge is a late-ripening species whose name derives from the perianth bristles that give the inflorescence a fuzzy or wooly appearance. The Ojibwa used common woodsedge for weaving bags and mats, and the Potawatomi used the fruiting heads to stuff pillows.

Scirpus cyperinus (Wool Grass) is an emergent aquatic perennial forming a dense tuft of arching basal green leaves and erect stems (culms). Each culm has 5-10 ascending to spreading leaf blades, and is topped in summer by a compound umbel, 4-6 in. long (10-15 cm), of many spikelets on branching rays.

Woolgrass showcases an erect growth habit with soft, brush-like inflorescences towering above the ground at heights of up to 5 feet (1.5 meters). Its green stems are sharply triangular in cross-section and bear narrow, grass-like leaves.
