Vallisneria americana, commonly called wild celery,water-celery,tape grass,eelgrass, or flumine-Mississippi is a plant in the family Hydrocharitaceae, the "tape-grasses". Contrary to the implications of one of its common names, wild celery bears little to no resemblance to the celery used as a vegetable. Vallisneria americana grows under water and is consumed by various animals, including the canvasback. The plants themselves are long, limp, flat, and have a green mid-ridge.
