PhenologyFlowering and fruiting July-October.
IdentificationThis grass typically grows in populations of scattered individuals. The stems grow 2-4 feet tall, with a terminal inflorescence from 6 inches to 1.5 feet long and composed of a series of well-spaced, gray-green or whitish whorls. Sometimes the whorls are all swept to one side of the stem and arched. C. latifolia occurs only in the Mountains and differs by a more open inflorescence with fewer whorls, and it has smaller spikelets (usually 2.5-4 mm long vs. 4.5-6 mm long in C. arundinacea).
