Summary

Elymus villosus, commonly known as Hairy Wildrye, is a perennial grass that exhibits semi-evergreen to deciduous behavior depending on the climate. It is native to a variety of habitats including open woodlands, forest edges, and grasslands in the Central and Eastern USA. This species typically reaches a height of 2 feet (0.6 meters) and a width of 1 foot (0.3 meters), featuring a tufted growth form with fine-textured, hairy leaves that provide a soft, textured appearance in the landscape.

Hairy Wildrye is appreciated for its adaptability to various soil conditions and its ability to thrive in both full sun and part shade, making it a versatile choice for gardeners. It requires medium amounts of water and prefers soils with medium drainage. Its subtle green to blue-green foliage and ability to form dense clumps make it an excellent ground cover or accent plant in borders and naturalized areas. While not known for showy flowers, its seed heads can add visual interest in late summer to fall. It is relatively low maintenance and can be used for erosion control on slopes. Potential problems include rust and leaf spot, though these are not typically severe. It is not known to have aggressive roots or be particularly invasive.CC BY-SA 4.0
