Description Bush muhly is fairly understated most of the year, often appearing as a tangled mass of dry stems and leaves tucked under the covering of mesquite (Prosopis velutina) or other shrubs. This species occurs across western, central, and southern Arizona on rocky or sandy, well draining soils on slopes or wash margins. When (if) the rains come in the summer then this species springs to life, greening up and developing loose sprays of pinkish seedheads. These masses of densely branched grass plants are truly gorgeous, and this is one of the best grasses for arid gardens, as long as you are willing to accept the portion of the year where bush muhly is dormant.
