Achillea millefolium 'Cassis' 

🌿 Achillea millefolium 'Cassis' 

Achillea 'Cassis' offers vivid deep pink to rich raspberry-red flower heads that hold their colour beautifully through the summer months. Its finely divided, feathery foliage forms a neat mound, making it perfect for adding strong colour and soft texture to sunny borders. Highly drought-tolerant and low-maintenance, it’s a superb choice for Isle of Wight gardens seeking long seasonal colour.

Specifications:

• Height: 60–70cm

• Spread: 45–60cm

• Flowering: June to September ☀️🍂

• Position: Full sun

• Soil: Well-drained soil; thrives on sandy, stony, or chalky soils

🌿 Note for Isle of Wight planting:
Achillea 'Cassis' thrives in the island’s dry, sun-drenched gardens and copes well with coastal breezes. Plant in open, sunny borders with free-draining soil. Avoid overly rich ground to maintain compact, upright growth and vivid flower colour.
