Deergrass

Scientific Name: Muhlenbergia rigens

Muhlenbergia rigens, commonly known as deergrass, is a species of perennial bunchgrass native to the southwestern United States and northwestern Mexico. Deergrass is well-adapted to arid and semi-arid regions and is commonly found in a variety of habitats, including grasslands, chaparral, coastal sage scrub, and desert scrub. It prefers well-drained soils and is often seen on slopes or hillsides. Deergrass forms dense, clumping tufts with slender, arching, and graceful foliage. The leaves are narrow, linear, and can reach lengths of up to 2 feet (60 cm) or more. They are typically bluish-green or grayish-green in color.

Deergrass is an ecologically important plant in its native range. It provides food and habitat for various wildlife species, including deer, birds, and insects. Additionally, its dense clumps help stabilize soil and prevent erosion in areas prone to disturbance. Historically, indigenous communities in the southwestern United States utilized deergrass for various purposes, such as weaving baskets and mats.
