This native bunchgrass, Deergrass (Muhlenbergia rigens) is a popular plant choice for groundcover and lawn replacement applications. It's an attractive, low-water grass that's very easy to grow. Deergrass does best in sandy soil and full sun, but it is versatile enough to tolerate shade and a variety of soil types.

The leaf blades are pale green, and in spring the plant produces tall spikes of yellow flowers. The seeds provide food for birds in summer. Plant this large mounding grass in groups for an impressive display.

In inland mountain areas it may occur with Ponderosa Pine and other trees in yellow pine woodland or foothill woodland. In a few locations it may be found on seasonal stream banks or other wetland areas.

This is a large clumping grass, so use with shrubs that won't be overwhelmed by it, such as Toyon (Heteromeles arbutifolia), Lemonade Berry (Rhus integrifolia), larger Ceanothus, Manzanita species, or scrub oaks.
