Yellow oatgrass is a graceful, clump-forming ornamental grass that thrives in sunny meadows and well-drained soils with minimal care. It tolerates a range of soil conditions and requires little supplemental watering once established. Plant it in borders or naturalistic settings for its attractive golden seed heads that sway elegantly in the breeze.
