Schoenoplectus americanus (Olney threesquare)

Formerly Scirpus americanus. Also called Chairmaker bulrush. Cool season, rhizomatous, native grasslike perennial occurring in wet meadows, marshes and other low-lying sites. Tolerant of alkalinity but does not require it. Found at low to moderate elevations. May become dominant or co-dominant in slightly or moderately saline marshes bordering lakes or springs. Good for riparian reclamation. Roots and rhizomes are an important food source for geese and muskrats; nesting for numerous other species.
