Muhlenbergia rigens—deer grass

A dramatic, architectural presence seems to contradict the common name of this species—deer are not attracted at all. Easily grown in nearly any soil in full sun or part shade, its main preference is sunshine since it falters in heavy shade. Winter rains provide adequate moisture, but summer irrigation keeps foliage bright green. Long, thin blades arch gracefully and fountain-like in a broad mound 3 ft. high and 4 ft. wide. In summer, tawny flower stalks, radiating outward, carry very thin flower heads 3-4 ft. higher. Fast-growing, it can reach maturity from seedling stage in two seasons. Grassy mounds may be completely neglected for a couple of years without suffering; however, deer grass stays best looking when irrigated in the dry season, then cut down to 3 in. or lower every 1-3 years in winter before rapid regrowth in spring. In a natural environment, grasses can go years longer without pruning. Some gardeners groom occasionally by cutting out dead stalks and stems. A nearly identical, half-size, non-native version from Texas—pine muhly, M. dubia—may be more useful in small gardens.
