Festuca glauca, also known as blue fescue or hairgrass, is a perennial ornamental grass of the Poaceae family. It forms dense, compact clumps with narrow, linear leaves in a light gray-blue hue, reaching up to 14–18 cm in length. The plant typically stands about 30 cm tall, with airy mounds of pale green or bluish flowers emerging from its stems, blooming from late spring to early summer.

This grass prefers well-drained sandy or clay soils of medium fertility and thrives best in full sun or partial shade. It is drought-tolerant and thrives in low-nutrient conditions, though periodic watering during prolonged dry periods enhances its health. Festuca glauca is hardy in USDA zones 3–4, making it suitable for cold climates.

In landscape design, hairgrass is often used as a ground cover, border, or edging element, particularly when paired with hostas, sedums, and other ornamental grasses. Thanks to its fine leaf texture and low maintenance requirements, it provides year-round greenery while remaining low-maintenance and cost-effective.
