Cyperus erythrorhizos

SEDGE FAMILY (Cyperaceae)

This native umbrella sedge has grooved leaves about as long as its main stem (culm). Flower spikes are arranged in compound clusters (umbels). Each spike has numerous tightly arranged, flat spikelets, which turn a rich copper-color at maturity.

Flowers appear in August.  Found on muddy shores of streams and lakes. Abundant in Fontenelle Forest along the shore of the Great Marsh near the blind.

Yellow Nutsedge (Cyperus esculentus) and Fragrant Sedge (Cyperus odoratus) have more loosely arranged straw-colored spikelets.
