Summary

Elymus elymoides, commonly known as Squirreltail or Bottlebrush Squirreltail, is a deciduous perennial grass native to a variety of habitats including open woodlands, grasslands, and scrub areas in the Western USA and Canada. It typically grows to around 0.5 meters (20 inches) in height, forming dense tufts. The plant’s erect, solid stems bear flat or rolled leaf blades, contributing to its bunchgrass form. The inflorescence is particularly notable, reaching up to 15 centimeters (5.9 inches) long, stiff and erect, with spikelets one or two centimeters long not counting the awn, which may extend to 9 centimeters and sticks straight out at maturity. This bottlebrush-like appearance not only gives the plant its common name but also aids in wind dispersal of the seeds.

Squirreltail is valued for its drought tolerance and ability to thrive in poor soils, making it an excellent choice for xeriscaping and restoration projects. It is also used to stabilize soils and prevent erosion. In cultivation, it requires full sun, minimal water once established, and well-drained soils.CC BY-SA 4.0
