Tussock Cottongrass is one of the most characteristic plants of Arctic and boreal wetlands, forming large, elevated tussocks topped by fluffy white cotton-ball seed heads in spring. It dominates vast areas of Alaskan and Canadian tundra. Caribou and musk oxen graze the nutritious green leaves, and its seeds are used for nesting material by many tundra birds.
