Flowering - June - October.

Origin - Native to U.S.

Other info. - This striking grass can be found throughout much of Missouri but is apparently absent from the northwest and extreme southeast corners of the state. This species is probably the easiest of all the grasses to identify because of its drooping inflorescences and compressed spikelets. The spikelets turn a nice golden-brown color in the fall and are excellent for dried flower arrangements. The plant is also sold for cultivation and takes little care once established. It grows well from seed.
