Blue Oat Grass (Helictotrichon sempervirens) is an attractive ornamental grass known for its unique blue-gray foliage and graceful, fountain-like form. This perennial grass forms dense clumps of narrow, arching leaves that give the plant its distinct appearance. The foliage color intensifies to a blue hue as it matures. In the summer, it produces tall, slender flower spikes that emerge in a bronzy tint and turn a light tan as they age, adding an additional layer of visual interest. Blue Oat Grass is relatively low-maintenance and can tolerate a variety of soil conditions, though it thrives in well-drained soil and full sun. It's often used in gardens, landscapes, and rock gardens to provide a striking contrast and texture. This grass typically grows to a height of 2 to 3 feet and is a versatile choice for adding a touch of elegance to outdoor spaces.
