Molinia caerulea
A cool-season, dense, clumping grass, native from Europe to western Siberia; south to northern Africa to the Middle East. In warmer parts of its range, it is usually found in mountain meadows. In the British Isles, it is found on heaths and bogs.

Hardy zones 3 to 8 in full sun to partial shade on moist, acidic to very acidic, light soils. Tolerant of wet conditions. It is often slow to establish. Propagation is from division or seed.
