Bouteloua hirsuta, Hairy Grama, Ornamental Grass, Perennial grass, Drought tolerant grass

Bouteloua hirsuta (Hairy Grama) is a densely tufted, warm season, ornamental grass noted for its intriguing inflorescences, 20 to 50 per branch, resembling tiny brushes or eyelashes. Suspended horizontally from only one side of the flowering stems, the flowers are green to purple at first before they bleach to a straw color. On display from spring to fall, they rise above a foliage mound of flat or slightly rolled, narrow leaves covered with small hairs. Growing throughout much of North America, Hairy Grama prefers relatively dry conditions and is often found in sandy soils where water retention is low. It has shallow, fibrous roots, which may allow it to take advantage better of intermittent, sparse precipitation during the warm growing season. In the northern part of its range and in areas with sufficient precipitation, Hairy Grama may form a continuous groundcover. A good choice for water-wise and xeriscape gardens, where the curious comblike flower spikes can be enjoyed. Freely self-seeds and will naturalize over time. Birds may use it for nesting material and will eat the seeds.

  • Grows up to 10-30 in. tall (25-75 cm) and 12-18 in wide (30-45 cm).
  • Performs best in full sun to light shade, in dry to medium, sandy or rocky, well-drained soils. Drought tolerant once established.
  • Welcomed in any garden style, it is versatile and can be used as a specimen plant, in groups or en masse. It is ideal in borders where it provides texture, color and contrast. Great choice for rock gardens, prairies, naturalized areas. Can be used as a groundcover in dry spots. Flowers are excellent in dried arrangements.
  • No severe insect or disease problems.
  • Cut back old foliage to the ground in late winter.
  • Propagation by seed is difficult and rarely successful
  • Native throughout much of North America, including the Great Plains and Canadian Prairies region, as well as Mexico and Guatemala.
