Potamogeton alpinus
Also called Red Pondweed, Reddish Pondweed, Northern Pondweed
Alpine pondweed is a perennial submerged aquatic herb found in clean rivers and lakes across the Northern Hemisphere. It grows best in deep, fine mud with good water quality, and it is rarely grown on purpose because it competes poorly with other pond plants.
Potamogeton alpinus is a species of perennial aquatic plant known by the common names alpine pondweed and red pondweed. It is widespread in the northern hemisphere in both rivers and lakes with good water quality.
Potamogeton alpinus is not in widespread cultivation, and seems to be rather difficult to maintain, competing poorly with other pond plants. It is possible that this is related to its preference for a deep fine substrate. In common with other pondweeds of this group it roots poorly from stem cuttings and is best propagated by division of the rhizomes.
Red pondweed is native to much of the Northern Hemisphere, including Asia (Afghanistan, China (Heilongjiang), India (Assam), Japan, Kazakhstan, Korea, Myanmar, Pakistan, Russia, Uzbekistan), Europe (Austria, Belgium, Britain, Denmark, Estonia, France including Corsica, Germany, Ireland, Iceland, Latvia, Lithuania, Netherlands, Norway, Poland, Spain (Pyrenees), Sweden, Switzerland), Greenland, Canada, and the northern United States, especially the Rockies.
