Schoenoplectus pungens is a species of flowering plant in the sedge family known by the common name Common Three-Square.[2][3] It is a herbaceous emergent plant that is widespread across much of North and South America as well as Europe, New Zealand and Australia.[1][4][5][6][7][8][9][10]

Information

Schoenoplectus pungens is a long-lived perennial herb up to 1.5 m tall, found in open, sun-lit marshes and along the shores of lakes and ponds, in water up to 1 m deep. It is resistant to fire.[11][12][13][14] The species is closely related to S. americanus, and many S. pungens specimens have long been misidentified as S. americanus.[2]
