About Thread Leaf Sedge (Carex filifolia) 1 Nurseries Carry This Plant Carex filifolia is a species of sedge known by the common name threadleaf sedge.

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.
