Molinia caerulea
Molinia caerulea is a perennial herbaceous bunchgrass native to Europe, western Asia, and North Africa. It is a tussock-forming grass growing up to 120 cm tall with coarse, green, tapered leaves and distinctive long narrow purple spikelets arranged in a 15 cm panicle that flowers from July to September. The dense tussocks are very resistant to heathland fires, and the plant is highly tolerant of acidic soils found in moorland and bog habitats.
Aruncus dioicus
Thrives in the same partial sun, moderate water conditions as Purple moor-grass
Water: Medium · Height: 120 cm · Soil: Prefers acidic soils with pH 3.5–5.0; tolerates extreme acidity down to pH 2.0; grows best in moist heathland, bogs, and moorland.
These three thrive alongside Purple moor-grass — and alongside each other.
