Festuca glauca, commonly known as the Blue Fescue, Blue Mountain Grass, and Grey Fescue, is native to Europe. Many of the horticultural cultivars were selected in German nurseries. It was originally described by French naturalist Dominique Villars.

The etymological root of the binomial name Festuca is derived from the Latin festuca ‘stalk or straw’. Glauca is derived from the Greek glaucous ‘blue grey’.

Festuca glauca may be useful to the landscape architect as a low ground cover plant, when planted en mass, producing a distinctive hummocky texture. Once established this plant is drought tolerant.

The Royal Horticultural Society has awarded the variety Festuca glauca ‘Blaufuchs’ their prestigious award of Garden Merit 1993.

Festuca glauca prefers moist, well drained soil. It can tolerate quite poor soils and dry conditions. It will not tolerate heavy, wet soils or constantly high humidity.

Festuca glauca requires little maintenance. It may need to be replaced every 3-4 years as the centre tend to die out. Regenerative pruning may be carried out in late winter.
