| Distribution | Primarily a coastal and near-coastal species, found from the VA border south to Brunswick County. Also a few scattered inland records in the southwestern Coastal Plain and one site in the northern Mountains.
This is a widespread species across the continent, but is primarily coastal and Northern. There are numerous collections south to VA and MO, as well as in FL. | |
| Abundance | Fairly common to locally common in the eastern Coastal Plain, south to Carteret County. Very rare farther south and inland, though theoretically could be found in most any county. | |
| Habitat | This species grows submerged in still or slow-moving waters of estuaries, rivers, ponds, and lakes. It often can be found in brackish and oligohaline waters of Tidewater Sounds. | |
| Phenology | Flowers and fruits from July to October. | |
| Identification | This is a submerged grasslike plant with a number of essentially erect leaves emerging from a common base. The leaves are up to 2 feet tall, about 1/3-inch wide, and minutely serrate along the margins. Male flowers are numerous and break from a spathe to free-float on the surface, small, with 3 white petals and 3 white sepals. The also white female flowers are on long stalks that reach the water surface. Common Eelgrass (Zostera marina) is a similar plant but has shorter and more branched leaves, which are rounded at the tips and are strongly 3-5 nerved. Zostera grows only in strongly brackish tidal waters of sounds and bays, usually in very extensive beds. | |
