Festuca pallens, commonly known as blue fescue, is a perennial herbaceous plant, specifically a grass, native to temperate grasslands and rocky slopes in Europe. It is a clump-forming ornamental grass that typically grows to a height of 6-10 inches (15-25 cm) with a similar spread. Blue fescue is known for its fine, blue-gray foliage that forms a dense, tufted mound. It produces inconspicuous greenish flowers in early to midsummer, which mature into tan seed heads that are often left on the plant for winter interest.

Blue fescue is valued for its low maintenance, drought tolerance, and the striking blue color of its foliage, which adds contrast and interest to garden compositions. It is commonly used in rock gardens, as a border plant, or in mass plantings as ground cover. This grass prefers full sun to light shade and thrives in well-drained soils. Overwatering or heavy clay soils can lead to root rot, so proper drainage is essential. Blue fescue is relatively pest and disease-free but can suffer from rust in humid conditions. It is not known to be invasive and is often used in xeriscaping due to its low water requirements.CC BY-SA 4.0
