Eelgrass

Lawn & Garden

Eelgrass is a beautiful aquatic plant that grows underwater.

Although eelgrass is aesthetically pleasing, it mostly serves a practical purpose as an oxygenating plant that is not easily visible in its aquatic environment. The ribbon-like leaves of eelgrass are translucent and pale green, with small white flowers that are barely noticeable. In winter, it loses its leaves and goes dormant in zone 10, but is generally easy to care for.

Eelgrass is typically sold as a single rooted plant instead of clusters of cuttings. To grow this plant, its pot should be sunk 6 to 24 inches underwater, and it can grow in sun, partial shade, or shade. Eelgrass produces runners that root when they touch the soil, which can be cut and grown separately.

Eelgrass is an excellent oxygenator and is popular with fish for spawning and as a food source. Other submerged sagittarias, such as S. graminea and S. natans, perform similar functions and look like eelgrass. The scientific name of eelgrass is Vallisneria americana.
