Cotton grass is a perennial sedge characterized by its grass-like foliage and distinct cotton-tufted flower spikes. Its slender leaves are typically pale green and can reach lengths of up to 20 inches (50 cm). The plant’s most striking feature is its white, fluffy seed heads, resembling tufts of wool, which emerge in late spring and can persist into the fall. These seed heads are supported by triangular stems that can grow up to 3 feet (90 cm) tall. The plant thrives in moist, acidic soils and can often be found in sun-dappled to partially shaded areas.
