Helictotrichon sempervirens | Blue Oat Grass
DESCRIPTION
Helictotrichon sempervirens, or Blue Oat Grass, is a perennial grass known for its silvery-blue foliage and elegant form. Its narrow, arching leaves create a dense, fountain-like clump, adding cool texture to garden landscapes. The fine-textured blades maintain their ornamental value throughout the growing season, making it a popular choice for adding contrast in garden beds, borders, and containers.
In mid to late summer, Blue Oat Grass produces airy flower spikes that rise above the foliage. These delicate panicles start pale green and mature to a soft, straw color, enhancing the plant's refined appearance. Its combination of soothing color and graceful form makes it an ideal addition to a variety of garden settings.
