Canada Pond Weed - Elodea canadaensis

Aquatic freshwater plant found in ponds and lakes but not acid waters. Very fast growth being able to choke a pond very quickly. Submerged stems carrying rings of six to twelve backward facing lance shaped leaves, very small flowers rarely observed.

Can be controlled by clearing by hand or specialised machines, but will regrow from any portion of the plant left behind. In the last few years Canada Pond Weed has regionally suffered a serious die back, of, as yet an unknown cause and has not been seen in the Brickfields pond for over two years.
