Curlyleaf Muhly: A Southwestern Native Grass Worth Getting to Know

If you’re looking for a low-maintenance, drought-tolerant grass that adds unique texture to your landscape, curlyleaf muhly (Muhlenbergia setifolia) might just be your new best friend. This charming native grass has a personality all its own, with distinctive curly leaves that set it apart from your typical lawn grass.

What Makes Curlyleaf Muhly Special

Curlyleaf muhly is a perennial grass native to the southwestern United States. True to its name, this grass produces narrow, thread-like leaves that curl and twist, creating an almost whimsical texture in the garden. The plant forms neat, compact clumps that stay relatively low to the ground, making it perfect for areas where you want interesting foliage without towering height.

In late summer and fall, curlyleaf muhly produces delicate, airy seed heads that catch the light beautifully and add movement to the garden when they sway in the breeze. While the flowers aren’t showy like those of wildflowers, they have their own subtle charm.

Where You’ll Find It Growing Wild

This southwestern native calls Arizona, New Mexico, and Texas home. In the wild, you’ll typically find it growing in rocky areas, desert grasslands, and on hillsides where the soil drains well and water is scarce.

Why Consider Planting Curlyleaf Muhly

There are several compelling reasons to give this native grass a spot in your landscape:

  • Drought tolerance: Once established, this grass can handle extended dry periods with minimal to no supplemental watering
  • Low maintenance: It requires very little care once it’s settled in
  • Unique texture: The curly foliage adds visual interest and contrasts beautifully with other plants
  • Native benefits: As a native plant, it supports local ecosystems and requires fewer resources
  • Wildlife value: While not a major pollinator plant, the seeds provide food for birds and small mammals

Perfect Garden Settings

Curlyleaf muhly shines in several landscape situations:

  • Rock gardens: Its low-growing habit and drought tolerance make it ideal for tucking between boulders
  • Xeriscaping: Perfect for water-wise landscapes
  • Native plant gardens: Pairs beautifully with other southwestern natives
  • Erosion control: The dense clumps help stabilize soil on slopes
  • Ground cover: Creates interesting textural carpets in larger plantings

Growing Curlyleaf Muhly Successfully

Hardiness and Climate

This grass thrives in USDA hardiness zones 7-10, making it suitable for most of the southern and southwestern United States. It’s well-adapted to hot, dry climates but can handle some cold as well.

Ideal Growing Conditions

Curlyleaf muhly is refreshingly easy to please:

  • Sunlight: Full sun is best, though it can tolerate some light shade
  • Soil: Well-draining soil is essential – sandy or rocky soils are ideal
  • Water: Drought-tolerant once established, but appreciates occasional deep watering during extreme heat
  • Soil pH: Adaptable to various soil pH levels

Planting and Care Tips

Getting your curlyleaf muhly off to a good start is straightforward:

  • Best planting time: Spring, after the last frost
  • Establishment: Water regularly the first year to help roots establish
  • Spacing: Plant clumps 12-18 inches apart for ground cover effect
  • Maintenance: Cut back old growth in late winter if desired, though it’s not necessary
  • Fertilizer: Generally unnecessary – this grass thrives in lean soils

The Bottom Line

Curlyleaf muhly is one of those wonderful plants that asks for very little but gives back plenty in terms of texture, drought tolerance, and native plant benefits. While it may not be the showiest plant in your garden, it’s the kind of reliable, interesting character that makes a landscape feel complete. If you’re gardening in the Southwest or have a hot, dry spot that needs something special, curlyleaf muhly deserves serious consideration.

Plus, there’s something deeply satisfying about growing a plant that’s perfectly adapted to your local conditions – it’s like working with nature instead of against it. And really, isn’t that what good gardening is all about?
