Carex
Carex is a genus of plants in the family Cyperaceae, commonly known as sedges. Other members of the Cyperaceae family are also called sedges, however those of genus Carex may be called "true" sedges, and it is the most species-rich genus in the family. The study of Carex is known as...

Description
Carex nebrascensis produces upright, angled, spongy stems up to about 90 centimeters tall. The waxy, bluish leaves form tufts around the base of each stem. The root system is a very dense network of rhizomeRhizome
