Lake Sedge is one of the tallest native sedges in North America, reaching 3–5 feet in height. It forms dense colonies along lake shores and in marshes from the Great Lakes region south to the Gulf Coast. Its broad, strap-like leaves are blue-green and provide excellent cover for waterfowl. This species plays a key role in stabilizing shorelines and filtering runoff.
