Potamogeton gramineus
Also called Various-leaved Pondweed, Grassy Pondweed, Grass Leaf Pondweed, Grass Leaved Pondweed, Variable Pondweed, Variable Leaved Pondweed, Various Leaf Pondweed
Variableleaf pondweed is a submerged aquatic perennial from the Northern Hemisphere that grows in shallow, clean water. It is grown mainly as an ornamental for garden ponds and barrels, where it needs clean, still or slow water.
Potamogeton gramineus is a species of aquatic plant known by the common name various-leaved pondweed, variableleaf pondweed, grass-leaved pondweed or grassy pondweed, native to the northern hemisphere where it grows in shallow, clean water.
Potamogeton gramineus is not in general cultivation, though it is an attractive plant and grows well in a garden pond or barrel. Its slower growth than most submerged species, attractive leaves and habit of producing a limited number of floating leaves make it very ornamental and suitable for garden ponds, and its smaller size than many other pondweeds is also a benefit. In common with other pondweeds of this group it roots poorly from stem cuttings and is best propagated by division of the rhizomes.
Potamogeton gramineus is native to much of the Northern Hemisphere, with a Holarctic distribution. It occurs in northern Europe (Britain, Ireland, Iceland, Scandinavia, Germany, Switzerland, France, Poland, Russia, the Baltic States), Greenland, North America (US except for the southeast, Canada). There are outlying populations in southern Europe (Iberia, Corsica, Italy), Caucasus, Pyrenees, and western US.
