Description A common grass South of I-40 in Arizona where it is found on slopes, often in association with other native grass species such as grama grasses (Bouteloua spp.) and Muhly grass (Muhlenbergia spp.). This species can get quite a bit taller than other grasses, often reaching 3-4 feet with airy, open inflorescences (flowering heads). The wide elevation range of this species makes it a good candidate for gardens in the desert up to those In oak/juniper woodlands. Interplant with other native grasses, for a layered effect.
