Blue Oat Grass (Helictotrichon sempervirens)

Blue Oat Grass is a striking ornamental grass known for its silvery-blue foliage, which forms dense clumps that provide texture and contrast in the garden. The grass is upright and arching, creating an attractive, fountain-like shape. In late spring or early summer, it produces light, airy flower spikes that add to its ornamental value. Blue Oat Grass is drought-tolerant and works well in dry, well-drained soils. Its cool-toned foliage contrasts beautifully with warm-toned flowers and plants, making it an excellent addition to modern, minimalist, or prairie-style gardens.
