Aristida laxa, commonly known as Sand Wire Grass or Slender Threeawn, is a perennial grass native to the Americas. It is adapted to dry, infertile, and fire-prone habitats. This grass typically grows at a moderate rate to a height of 1-3 feet (0.3-0.9 meters) and is noted for its fine-textured foliage and wiry appearance. The flowers are brown and inconspicuous, blooming in the summer, and are followed by distinctive three-awned seeds that can persist into winter, providing visual interest and food for wildlife.

Sand Wire Grass is valued for its drought tolerance and ability to thrive in poor, sandy soils, making it suitable for xeriscaping and restoration projects. It is often used in naturalistic plantings, as a ground cover in sunny areas, and for erosion control on sandy sites. In cultivation, it requires full sun and well-drained, sandy soils. It is low-maintenance, needing minimal water once established, and does not require fertilization. However, it can be sensitive to overwatering and excessive nutrient availability. While generally disease-free, it can be outcompeted by more aggressive species if not managed properly.CC BY-SA 4.0
