What is Cliff Muhly?

Cliff muhly is a native perennial grass that belongs to the graminoid family – essentially the grass and grass-like plant crew that includes true grasses, sedges, and rushes. True to its name, this hardy plant naturally grows on rocky slopes, cliffs, and canyon walls throughout its native range.

Where Does Cliff Muhly Grow Naturally?

This southwestern native calls Arizona, New Mexico, Texas, and Utah home. You’ll find it clinging to rocky outcrops and thriving in places where many other plants simply can’t survive. It’s perfectly adapted to the challenging conditions of the American Southwest.

There are plenty of reasons to fall in love with this resilient native grass:

  • Drought tolerance: Once established, cliff muhly needs very little water – perfect for water-wise gardening
  • Low maintenance: This tough plant pretty much takes care of itself
  • Aesthetic appeal: Forms attractive fountain-like clumps with fine-textured foliage and delicate seed heads that dance in the breeze
  • Wildlife support: Seeds provide food for birds and small mammals, while flowers support native insects
  • Soil adaptability: Thrives in poor, rocky soils where other plants struggle

Perfect Garden Situations for Cliff Muhly

This versatile native grass shines in several landscape scenarios:

  • Native plant gardens
  • Drought-tolerant landscapes
