About Common Yellow Lake Sedge

Common Yellow Lake Sedge (Carex utriculata), also known as Northwest Territory Sedge or Beaked Sedge, is a dominant and attractive wetland plant known for its bright, yellowish-green foliage. Growing up to three or four feet tall, this perennial sedge features relatively thin, hairless leaves that often arch over the large, inflated seed spikes that appear from June through August. These prominent 'beaked' seed heads are a defining characteristic, providing both visual interest and a bounty of food for wildlife. Native across a wide swath of northern North America, it is a primary component of subarctic and temperate wetlands, often found growing in shallow water or saturated mud. It thrives in full sun and wet to medium-wet conditions, where its aggressive rhizomes help it form dense stands. This sedge is a vital ecological player, providing essential habitat for waterfowl and serving as a host for numerous wetland insects. Its bright color and vigorous growth make it an excellent choice for large-scale pond naturalization or wetland restoration projects.
