Curly-Leafed Pondweed

Potamogeton crispus



Curly-leafed pondweed is a perennial plant that is native to Europe and gets it name from the rippled or wavy nature of its submerged leaves. The leaves are alternate, oblong 3/4 to 4 inches long and 1/4 to 1/2 inch wide. Mature leaves are toothed with a distinct midrib with paired parallel lateral veins, nearly translucent. Stems are flattened and branching. Fruits are seldom found, they reproduce from small “burr-like” vegetative structures that from a the base of some leaves. Curly-leafed pondweed can be an aggressive invader that can cover large portions of ponds.

Since fruits are not usually present on curly-leafed pondweed, it has little food value to wildlife. It is a non-native plant and should not be spread.
