Muhlenbergia tricholepis, commonly known as Hairy Awn Muhly, is a perennial grass native to the Southwestern United States and Northern Mexico, particularly thriving in desert mountains and arid grasslands. It is often found on dry, rocky hillsides and slopes, reflecting its adaptation to harsh, drought-prone environments. This grass typically grows at a moderate rate to a height and width of 1-2 feet (0.3-0.6 meters), forming dense clumps. The foliage is fine-textured, and in the fall, it produces purple or brown flowers that, while not showy, add a subtle beauty to the landscape. The flowers are borne on delicate, hair-like awns, which give the plant its common name.

Hairy Awn Muhly is valued for its drought tolerance and ability to thrive in poor soils, making it an excellent choice for xeriscaping and naturalistic plantings. It is also used for erosion control on slopes and banks. In cultivation, it requires minimal maintenance, thriving in full sun and well-drained sandy or loamy soils. It is a low-water-use plant, ideal for water-wise gardens. While it is not commonly afflicted by diseases or pests, overwatering or poor drainage can lead to root rot.CC BY-SA 4.0
