Muhlenbergia emersleyi, or Bull Grass, is an evergreen dense grass with a slightly coarse texture and long blue-green leaves. During the fall months, it produces masses of loose, rosy-purple flower spikes, which dry to a tan color in the winter.

This clump grass forms dense colonies in oak woodlands from Arizona to Texas. Drought-tolerant and thrives in full sun, reflected heat locations, and part shade. Vigorous spring pruning will remove any dormant foliage and flower spikes.
