Muhly Grass, commonly known as hairgrass, is a tough, Florida and Mexico native grass useful in many different landscape settings. Its glossy, wiry, thread-like, dark green leaves have a wispier look than most ornamental grasses. The most distinguishing feature about this grass is its fall flower. Masses of billowy inflorescense of massed, pinkish-red flowers rise above the foliage in a beautiful fall bloom lasting for six to eight weeks. The flowers produce tan seed plumes that are less than half an inch long and remain attractive in the winter.
This easy to grow ornamental grass produces clumps that can reach three to five feet tall and up to three feet wide when mature. Best grown in sandy or rocky, well-drained soil in full sun to light shade. It has an extreme tolerance to drought and flooding making it suited for wetland sites as well as beach front landscapes.
Muhly grass adds a nice, fine-texture for landscapes. It makes a spectacular groundcover when planted in masses and does well in edging and borders as well as centerpieces. Even after the flower stalks fade, thanks to its slender, dark green foliage, it still looks good in the landscape.
