Purple Three Awn

Purple Three Awn can be an important livestock forage species in areas of limited grazing; however, it can be invasive in certain situations, and its matured sharp awns can be problematic. It has some value as a landscape species for its drought tolerance.

Good source of livestock forage in arid areas where other forage species are limited. Provides habitat for small mammals and native bees. Used in native, water conserving landscaping.

Description

Menard Purple Threeawn is a native, warm season perennial bunchgrass that grows 1-3’ in height.  The purple tinged, three-awned, pointed seeds give the species its name.  Purple Threeawn is a common range grass on all soil types and it provides a substantial amount of grass cover in many areas of Texas. It is considered poor forage for livestock, but it can be an important cover species on disturbed and degraded sites. It has some value as a landscape species for its drought tolerance and coloration.  Purple Threeawn is useful for erosion control plantings, range and wildlife habitat restoration, and right-of-way revegetation and reclamation throughout Texas. 

Menard Purple Threeawn was developed for release by the Texas Native Seeds Program and the USDA NRCS Texas Plant Materials Centers. It is a blend of native populations from the Blackland Prairies, Cross Timbers, Rolling Plains, Edwards Plateau, Rio Grande Plains, and Gulf Coast Prairies and Marshes Ecoregions.  It is broadly adapted for use across the state.
