Carex crawfordii, also known as Early Fen or Crawford's Sedge, is a perennial sedge native to Michigan but more common in the Upper Peninsula. It is a clump-forming sedge that likes dry, sandy soil. It is reported as favoring Lake Superior dune areas in addition to the richer moist soils in fens, swamps, and bogs; disturbed areas; and forest edges.
 
This sedge is a height of 18 inches to 3 feet tall. It has attractive foliage and interesting bronze seedheads. Sedges are the host plants for skipper and duskywing butterflies. They also provide seeds for birds and resources for other insects.
