American pondweed is a perennial plant that has both floating and a few submerged leaves in an alternate pattern. The floating leaves are elliptical to oval 4 to 7 inches long and to 2 1 inches wide on long petioles. Submerged leaves are not abundant and are blade-like, somewhat transparent and smaller than floating leaves. Rhizomes are white. The stem is rust colored and branched in 3s. Fruits are on spikes that often stand above the water’s surface and are brownish to reddish 3 to 2 1 inches long and 1/8 to1/4 inches wide.
This plant occurs throughout Texas in streams and lakes. The fruit matures in late spring and summer.
American pondweed is highly utilized as food by ducks and some other types of wildlife.
