Elijah blue grass landscaping plants are a cool-season, ornamental grass that grows in a small dome-shaped bunch. ”Elijah Blue” features long, silvery-blue blades that grow from about 6 to 12 inches high. Tufted clumps spread about 8 to 12 inches wide. Plants prefer full sun, but can live in partial shade. They grow well in a variety of rocky and shallow soils and pH, can tolerate winter salt spray, heat and periods of drought. “Elijah Blue” grass blades bloom in June and July with tiny flowers. Pests usually are not a problem, but overly wet soil may rot the grass’ roots. Trimming dead blades allows new leaves to grow. Tufted grass clumps should be divided every two to three years in early spring. Whether you grow Elijah blue fescue as ground cover or use it to adorn a border or rock garden, properly planting it in your garden is essential to your success.
