Blue fescue, botanically known as Festuca glauca, is a compact ornamental grass valued for its fine-textured, blue-gray foliage and clump-forming habit. It develops dense tufts of narrow leaves and produces small flower spikes during the growing season. This plant adapts well to temperate climates and performs best in full sun with well-drained soil. Blue fescue is commonly used in borders, rock gardens, edging, and container planting, where it establishes steadily from seeds and tolerates dry conditions once established.
