Sideoats Grama

Bouteloua curtipendula

Also known as Side-Oats Grama, Mesquite Grass, Bandera Grass

Sideoats grama forms dense clumps of narrow foliage topped by distinctive zig-zag stalks where oat-like seed spikes dangle along just one side. This warm-season grass blooms in summer with tiny purple and red anthers that sway gracefully in prairie breezes. Its deep fibrous root system makes it exceptionally drought-tolerant and vital for stabilizing prairie soils across North and South America.

Responsible observation
  • Identification: Look for seed heads lining only one side of the slender stem, hanging downward like tiny oats.
  • Landscaping: Plant in well-drained soil and full sun to form a drought-tolerant native ornamental meadow.
  • Prairie Restoration: Observe how its deep roots help prevent soil erosion on dry, rocky slopes.
