Summary

Muhlenbergia emersleyi, commonly known as Bullgrass, is an evergreen perennial grass native to open woodlands, grasslands, and rocky slopes in the Southwestern USA, particularly in Arizona and New Mexico, as well as in parts of Mexico and Central America. It typically grows to a height and width of 2-3 feet (0.6-0.9 meters), forming dense clumps of fine-textured, blue-green foliage. The plant produces airy, purplish inflorescences in late summer to fall, which are highly ornamental and can add a soft, feathery texture to the landscape.

Bullgrass is valued for its drought tolerance and ability to thrive in poor soils, making it an excellent choice for xeriscaping and naturalistic plantings. It is also used for erosion control on slopes and in restoration projects. In cultivation, it prefers full sun to part shade and requires minimal water once established, making it a low-maintenance option for gardeners. It is adaptable to a variety of soil types, provided they have good drainage. While generally pest and disease-free, Bullgrass can occasionally suffer from rust in humid conditions.CC BY-SA 4.0
