Elodea canadensis, commonly known as Canadian waterweed, is a submerged aquatic plant native to North America. It typically grows in freshwater environments such as lakes, ponds, and slow-moving rivers. This plant features long, slender stems that can reach lengths of up to 3 meters and has whorls of narrow, green leaves that are about 2-4 cm long. Elodea canadensis plays a vital role in aquatic ecosystems by providing habitat and food for various organisms, including fish and invertebrates. It also helps improve water quality by absorbing nutrients and producing oxygen through photosynthesis, making it an important species for maintaining healthy aquatic environments.
