Large blue hairgrass is a short-lived, cool season, ornamental grass that forms hedgehog-like, dense, circular mounds of thin, bluish green blades which typically measure 12" tall and 12" in diameter. Flower panicles emerge glossy green in late spring and mature to silvery-white on stems typically extending 6-12" above the foliage mound.
No serious insect or disease problems. This grass may only live for 2-3 years, particularly if planted in the moist, fertile environment of a typical border.
Edging, massing as a ground cover, border fronts or rock gardens.
