Purple Moor Grass (Molinia caerulea): A Native European Grass with Airy Purple Panicles

Purple Moor Grass, Molinia caerulea, is a cool-season, clump-forming grass native to moors, heaths, and damp meadows across Europe and Asia. Its airy, purple-tinged flower panicles rise high above the foliage in summer.

Transparent Beauty

This grass forms a dense, neat tuft of narrow, green leaves 1–2 feet tall. In mid to late summer, very tall (3–5 feet), slender, transparent stems bear open, purple-brown panicles that sway delicately. The effect is a hazy purple cloud. The foliage turns golden in fall and often collapses in winter (deciduous).

Ecological Value

Molinia caerulea thrives in acidic, moist to wet soils in full sun to part shade. It is a key species in European moorland ecosystems. In gardens, it adds vertical transparency and movement. Many cultivars exist with varied heights and colors.
