Description

Blue Fescue or Festuca glauca is an ornamental grass prized for its fine, evergreen, bluish foliage. Forming a small, dense, rounded clump, it will fill the foreground of flower beds and rockeries. This grass comes alive with silvery, trailing spikelets in summer. It is drought-resistant, ideal for dry gardens without irrigation. It's easy and quick to sow, allowing for beautiful vegetation in just a few months.

Festuca glauca belongs to the Poaceae family. It is native to Central Europe and is naturally found in dry, rocky, or sandy environments. This perennial grass with a non-running crown forms dense and compact clumps, reaching 20 to 30 cm in height and gradually spreading up to 30-40 cm wide. Its linear, fine, and rigid foliage is grey-green with a bluish sheen, particularly vivid in full sun. It persists all year round, even in winter. The leaves are covered with a waxy film, providing its bluish appearance, also indicating excellent adaptation to dry environments. In early summer, Blue Fescue produces slender inflorescences in spikes of a light beige to golden hue, borne on stems slightly higher than the foliage. These inflorescences are subtle and add an extra touch of lightness. After flowering, they can be cut back to maintain the plant's appearance. Its dense and fibrous root system gives it excellent drought resistance, as well as good adaptation to poor and well-drained soils. This fescue can spread, self-seeding here and there in light soils.

Blue Fescue is very easy to grow and prefers sunny exposures and well-draining soils, even poor or stony ones. Sow in spring, directly in place or in pots, on a light and slightly moist substrate. Once established, it requires very little maintenance: moderate watering, an annual pruning in late winter to remove dry leaves and densify the foliage. It is perfect in a scree garden, on a slope, along path borders, in rockeries, and even as an alternative to lawn in dry terrain, in areas not too heavily trodden. Pair this grass with plants like sedums, lavenders, euphorbias and Stachys, for example. It also adapts very well to pot cultivation.

Planting and care

Spring is the ideal season for sowing Blue Fescue directly in place or under cover, when temperatures are around 20°C.

Use a light, well-drained and nutrient-poor compost. A mix of garden soil and sand is recommended to avoid excess moisture, to which Blue Fescue is sensitive.

Sow the seeds on the surface, then lightly cover them with substrate. Maintain constant moisture until germination, which usually occurs within 1 to 3 weeks.

Place the seedlings in a sunny spot, as Blue Fescue develops its optimal colouring under intense light.

Once the seedlings are sufficiently developed, thin them out to leave a space of 8 to 10 cm between each young plant.
