Blue moor-grass (Sesleria caerulea)

Blue moor-grass

Blue moor-grass is easily mistaken for other species in its family, including Alpine Cat's-tail and Purple Stem Cat's-tail, but you can tell the difference by the fact that this species is much shorter and grows in limestone rather than acidic soil. Unlike its name Blue moor-grass suggests, this species produces green foliage and purple blooms. The Scotch Argus butterfly's caterpillar loves blue moor-grass.

Soil Type

Water: Blue moor-grass thrives in humid conditions requiring consistent moisture. It is neither drought-tolerant nor overly fond of humidity, necessitating weekly watering. This plant flourishes in outdoor settings, particularly in rainy climates that support its natural precipitation needs.

Fertilize: For blue moor-grass, apply mulch or compost in early spring to enhance nutrients for roots and foliage. An annual organic top-dressing promotes growth, but avoid overfeeding to prevent root burn. Adjust the amount seasonally, water after application, and keep it clear from stems.

Pruning: Pruning blue moor-grass in early spring promotes healthy growth and maintains its shape. Remove dead leaves and trim old foliage to encourage new shoots, enhancing appearance and preventing overcrowding and disease. Use clean, sharp tools for effective pruning.

Propagation: Blue moor-grass is a resilient, perennial grass that thrives in diverse conditions and is often propagated by division. Ensure each section has roots and shoots, water adequately, and maintain soil moisture. Space divisions properly to promote air circulation and growth.

Repotting: Repot blue moor-grass in early spring every 2-3 years, using a container slightly larger than the root ball for growth. Ensure good drainage and post-repotting, place in moderate light, water regularly, and refrain from fertilization for a month to support recovery.
