Native to Eurasia, widespread in the western United States. A common grass that grows in almost any situation as a low, dense cover. Once it’s seed panicles emerge it becomes useless as a forage grass, with seeds that have sharp, stout awns.
A winter annual, seeds germinating in the fall and winter, and plants maturing by early summer.
Growth may be up to 2 feet high, with slender stems. Leaves emerge along the stems, and are rolled or folded noticeably.
Seed heads are panicles with only a few, open, widely separated spikelets that assume a drooping attitude as they mature and gain weight. The full panicle may be 8 inches long, light yellow and distinctly shiny. The spikelets are around 5/8 inch long, with the terminal flowers having awns that are up to 1 inch long.
