Eel Grass

Eel Grass, or Vallisneria, is a submersed plant that spreads through runners and sometimes forms tall underwater meadows. Leaves arise in clusters from their roots and have rounded tips and raised veins. Single white female flowers grow up to the water surface on very long stalks. Eel Grass has spread from the aquarium industry.

Also known as: Tape Grass
