    Common Woolgrass is a common plant over a large native range of all Minnesota down through eastern Texas over to central Florida up through all of New England into southeast Canada growing in wet or moist soils of swamps, marshes, ditches, moist or wet meadows, and along lakes, ponds, and various watercourses. It is a member of the Sedge Family and is a grass ally. but not a true grass. Its stems are solid and 3-angled. It begins as a clump perennial but in time it can spread to become a colony from rhizomes. It is a cool season plant. It is sold by some native plant nurseries for native plant landscapes, bog gardens, or to be used by conservation organizations to control water erosion around ponds, lakes, and watercourses. It is not sold by conventional nurseries for ornamental purposes, so far.
