Eelgrass, tapegrass, water-celery, or wild celery are all common names for Vallisneria. Eelgrass is a rooted submerged plant often found in flowing water. It has long, thin, ribbon-like leaves (1/2 – 3/4 inches wide) that are commonly 3 to 4 feet long and clustered. The vein pattern in the leaves of eelgrass is very distinctive and resembles celery. Eelgrass has a vast rhizome system that allows it to form dense colonies and usually excludes other submerged plants.
This plant occurs in lakes and beds of flowing water. Eelgrass seeds, roots and leaves are consumed by ducks and other waterfowl, while its dense underwater structures provides an excellent Habitat for invertebrates and fish.
