Multiplication
seed
Quand planter
spring, autumn
Hivernage
Leave the foliage standing through winter to protect the crown from frost. Cut back to the ground in early spring before new growth begins.
En pot
It is not typically grown in containers as it prefers the stability of open ground.

Seed sowing

  1. Collect seeds in late summer when they turn brown.
  2. Sow directly into prepared soil in autumn.
  3. Lightly rake the seeds into the surface.
  4. Keep the area moist until germination occurs.

Pair this grass with native wildflowers to create a balanced meadow ecosystem.

Bonnes associations

  • Red clover — It fixes nitrogen in the soil, which benefits the grass.
  • Ox-eye Daisy — They grow well together in traditional meadow settings.
