Potamogeton foliosus is a perennial herb growing from a dense, mat-forming rhizome that anchors in wet substrate. It produces a thin, compressed, multibranched stem growing to a maximum length around 75 centimeters. The delicate, hairlike leaves are up to 10 centimeters long. They are pale green to olive green or reddish in color. The inflorescence is a small cluster or spike of flowers arising from the water on a short peduncle. Turions are sometimes present.[4][3]
