Description 1

A bushy, aquatic, submerged, perennial, dioecious plant with white roots that are not branched and are feathery. Large, flexible stalks that are rounded in the transversal section and 20-30 cm long, branched and very dense. Pale green leaves, in whorls of 3 (sometimes 4), that are sessile, linear or narrow spear-shaped with a softly jagged edge. Small white flowers (with a diameter of no more than 8 mm), 3 sepals and 3 petals.

Biology 1

In Europe there are only female specimens, thus they reproduce asexually by stalk fragments that take root.

Habitat 1

They prefer still or slow flowing, eutrophic (oligotrophic -mesotrophic) water that is rich in calcium. They can grow deeper than E. canadensis.
