About

Potamogeton obtusifolius, known as blunt-leaved pondweed, is an aquatic plant in the genus Potamogeton. It grows mainly in mesotrophic to eutrophic lakes, ponds and ditches, rarely in brackish water. It occurs primarily in Central Europe, the British Isles, Fennoscandia and eastern North America.

How to grow it

Blunt-leaved pondweed is not presently in cultivation. Although its wide ecological tolerance suggests it may not be difficult to grow, it would probably require a deeper substrate than is usual in most ponds. It can also be grown in aquaria by anchoring the turions in sand or mud. It is also likely to compete poorly with other pond plants.

Where it grows

Potamogeton obtusifolius has a wide global distribution, occurring in North America (Canada, northern US), Europe (Scandinavia, Central Europe, N Balkans, Great Britain, Ireland, France, N Spain), Asia (NE China (Heilongjiang Province), Russia, Japan, Kazakhstan, Kyrgyzstan, Mongolia, Myanmar, Caucasus, Iran).
