This tough, drought-tolerant native grass brings both practical benefits and natural beauty to gardens across the American Southwest.
What Makes New Mexico Bluegrass Special
New Mexico bluegrass is a perennial grass that’s perfectly adapted to life in the challenging conditions of the southwestern United States.

This resilient grass calls Arizona, Colorado, New Mexico, and Texas home, where it grows naturally in a variety of habitats from grasslands to open woodlands. As a true native of the lower 48 states, it’s perfectly suited to the unique growing conditions of the Southwest.
