Sheep's fescue
The fine green matrix everything else grows through.

The green matrix
A meadow isn't flowers on dirt — it's flowers in grass. Sheep's fescue is the fine, low, drought-tolerant grass that gives the whole thing its structure without swamping the flowers.
Specs
type fine grass, native height 15–40 cm flower (none — it's the frame) soil dry, poor seed 2 g / m² in a mix
Why we sow it
Fertile soil grows coarse rye that smothers everything. Fescue is the polite grass — it sits low, opens up gaps, and lets the flowers do the talking.
