Bottlebrush Squirreltail
Elymus elymoides
  
About Bottlebrush Squirreltail (Elymus elymoides) Nurseries Show All Photos Elymus elymoides is a species of wild rye known by the common name squirreltail. This grass is native to most of North America west of the Mississippi River. It occurs in a number of ecosystems, from alpine forest to desert sage scrub to valley grassland. It is a perennial bunch grass growing to around half a meter in height. Its erect solid stems have flat or rolled leaf blades. The flower cluster is up to 15 centimeters long and somewhat stiff and erect, with spikelets one or two centimeters long not counting the awn, which may be 9 centimeters long and sticks straight out, making the flower cluster look like a bottlebrush. This grass is considered a very good forage for sheep. It is best for grazing during the winter, when it is small and green. It becomes less palatable to livestock when its awns grow long and sharp at maturity.
