The Labrador tea shrub is a heath with aromatic leaves that will grow up to six feet tall in regions south of the tundra. Heaths are found in the low arctic tundra and the smallest, hardiest dwarf heaths are found in the mid-arctic tundra. No heaths can withstand the conditions of the northern-most high tundra. And the Salix Arctica, the Arctic willow, is a tiny creeping willow. It is adapted to survive in Arctic conditions, specifically tundra's. Eriophorum (cottongrass, cotton-grass or cottonsedge) is a genus of flowering plants in the family Cyperaceae, the sedge family. They are found throughout the arctic, subarctic, and temperate portions of the Northern Hemisphere in acid bog habitats, being particularly abundant in Arctic tundra regions.
