• The subspecies pubescens is really endemic to serpentine soil.
• It can thrive on sunny, dry and low fertility soils.
• Needle grass is valued because of its soil stabilization and revegetating strengths.
• It is named for its spike-like seeds.
• It may star in naturalized areas with little foot traffic.
• This is perhaps a large part as a native ornamental grass.
