Muhlenbergia polycaulis, commonly known as Cliff Muhly, is a perennial grass that exhibits semi-deciduous to evergreen behavior depending on the climate. It is native to rocky slopes, canyons, and desert grasslands in the Southwestern USA and Northern Mexico. This grass typically reaches a height and width of 1-2 feet (0.3-0.6 meters), forming dense clumps of fine-textured foliage. The inflorescences are airy and delicate, providing a subtle visual interest when they bloom in the late summer to fall.

Cliff Muhly is valued for its drought tolerance and ability to thrive in poor, rocky soils, making it an excellent choice for xeriscaping and naturalistic plantings. It is often used in rock gardens, as a ground cover, or for erosion control on slopes. This grass prefers full sun to part shade and requires minimal water once established, reflecting its adaptation to arid environments. It is also appreciated for its low maintenance requirements and its ability to attract wildlife, such as birds that feed on its seeds.CC BY-SA 4.0
