Potamogeton compressus
Also called Wrack Like Pondweed
Grass-wrack pondweed is a rare, annual aquatic plant with strongly flattened stems and grass-like leaves that grows in slow or still water. It is not in cultivation, and the key to any attempt to grow it is clean, silty, regularly cleared ponds that keep out more competitive plants.
Potamogeton compressus is a species of aquatic plant known by the common names grass-wrack pondweed, flatstem pondweed and eel-grass pondweed.
Potamogeton compressus is not in cultivation. It could probably be cultivated in rather silty ponds, so long as they are regularly cleaned out in order to prevent other more competitive plants from excluding it. Cultivation experiments for conservation purposes have successfully grown plants to maturity from turions planted in late winter, but adult plants are more difficult to establish due to their limited root system and fragile nature. High mortality was also observed due to snail predation in culture.
Potamogeton compressus is native to Europe (Austria, Britain, Denmark, Finland, France, Germany, Ireland, Netherlands, Poland, Russia, Spain, Sweden, Switzerland, Ukraine), Asia (China (Yunnan), Japan, Kazakhstan, Mongolia, Russia).
