Festuca glauca is a short-lived exotic grass which is native to Southern France.  It was originally described by French naturalist Dominique Villars. This clump-forming ornamental grass is noted for its glaucous, finely-textured, blue-grey foliage. The foliage forms a dome-shaped, porcupine-like tuft of erect to arching, needle-like 9-ribbed blades, radiating upward and outward to a length of 140-180 mm. Light green flowers with a purple tinge appear in terminal panicles atop stems rising above the foliage in late spring to early summer, but inflorescences are not very showy. Flowers give way to puffy wheat-like seed-heads. It is drought tolerant and will grow in poor soils, but it is intolerant of wet or poorly-drained soils.
