Eriophorum scheuchzeri is a species of flowering plant in the sedge family known by the common names Scheuchzer's cottongrass and white cottongrass. It has a arctic circumpolar and circumboreal distribution in the Northern Hemisphere. It can be found in Alaska, across Canada, in the Arctic islands, Greenland, Iceland, and across Eurasia. There are disjunct occurrences in the Rocky Mountains, in the high mountains of southern Europe (the Pyrenees, Alps and the Caucasus) on Mount Daisetsu in Japan and some other Asian mountains.
This species is a perennial herb producing colonies via its rhizome. The thin stems may reach 70 centimetres (28 in) tall, but they are often much shorter. The rolled leaf blades are up to {convert|12|cm}} long. Leaves at the top of the stem have no blades, just black-tipped sheaths. The inflorescence is a solitary flower head with wispy, cottony, bright white, red-tinged, or silvery bristles up to 3 centimetres (1.2 in) long.
This plant can be found at sea level in northern parts of its range and at over 4,000 meters (13,000 feet) in elevation farther south. It is a helophyte. It is restricted to wet habitat types. It grows in marshes and wet meadows, by ponds and lakes, and on riverbanks, in moist and wet gravel and sand substrates. It often lines the edges of standing water bodies. It is commonly associated with mosses and other sedges, such as Carex aquatilis.
