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. Blue fescue grass ( Festuca glauca) is a colorful ornamental grass with icy blue foliage and pale yellow flowers. It is drought-tolerant and grows in USDA plant hardiness zones 4 through 8. Gardeners like its ease of care and its fine texture, which makes it a good companion plant for heavier or more dramatic plantings.
This plant has average moisture needs. Water weekly during hot summer months to keep it green and growing; short periods of drought will stunt, but not kill the plant.
Mulching with a 3-inch layer of bark mulch or other organic material is advisable, especially when fostering the growth of young plants. Blue fescue plants do not need fertilization as long as an organic mulch is used around the base of the grass. Keep the foliage looking its best by hand combing out the dead blades of grass and removing the flower heads.
Cut back the foliage in early spring to within a few inches of the ground. This will help make room for the new grass blades and will improve the look of the plant.
