Deschampsia cespitosa, or Tufted Hair Grass, is a graceful, clump-forming ornamental grass known for its fine, green foliage and airy, silvery-purple flower panicles in summer, adding texture and movement to gardens, thriving in sun or part shade and tolerating various moist to dry soils. Native to many regions, it's a low-maintenance, frost-tolerant perennial used in borders, meadows, and containers for a soft, shimmering effect that lasts through autumn and winter.
