About Thread Leaf Sedge (Carex filifolia) Carex filifolia is a species of sedge known by the common name threadleaf sedge. It is native to much of western North America, from Alaska to California and Manitoba to New Mexico, where it grows in moist and dry habitat. This sedge produces clumps of stems which are rounded or triangular, wiry, and angled or curved, reaching up to about 35 centimeters long. The root network is extensive and it forms sod. The leaves are narrow and rolled tightly, appearing quill-like. The flower cluster is up to 3 centimeters long and has flowers coated with reddish scales. The fruit is covered in a sac called a perigynium which is somewhat hairy. The plant produces some seeds, but mainly reproduces vegetatively.
