Blue fescue

Description

Festuca glauca, commonly known as blue fescue, is a species of flowering plant in the grass family, Poaceae. It is a commonly cultivated evergreen or semi-evergreen herbaceous perennial. F. glauca is a clump-forming ornamental grass noted for its glaucous, finely-textured, blue-gray 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.
