Largehead sedge (Carex macrocephala) is a perennial graminoid found in moist to wet habitats across northern North America and eastern Asia, including Alaska, British Columbia, Oregon, and parts of Japan and Russia. This plant thrives in light to partial shade and can tolerate various soil types, from sandy to clay-rich conditions. Known for its edible roots and seeds, largehead sedge is a valuable resource in native ecosystems and has been utilized by local communities. One distinctive feature of this species is its relatively large inflorescence compared to other sedges, making it easily recognizable in the field.
