Elegant, well-behaved, and beautifully architectural, Blue Oat Grass (Helictotrichon sempervirens) is one of the finest mid-sized blue ornamental grasses. It forms rounded clumps of gracefully arching, narrow, steel-blue leaves, creating a cool, refined accent in sunny gardens. Similar to Blue Fescue (Festuca glauca) but larger and more substantial, it brings year-round structure with very little care.
