Wil celery (Vallisneria americana) is a plant in the family Hydrocharitaceae (the "tape-grasses"). Contrary to the implications of its name, wild celery bears little to no resemblance to the Celery one may buy at the market. Wild celery 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. Animals may eat the entire plant (both the leaves and the underground tubers).
