About
Achillea millefolium 'Proa' is a robust perennial that typically reaches about 80cm tall, featuring finely dissected, fragrant green leaves. From summer through early autumn, it produces flat-topped clusters of pure white blooms. Once established, this plant shows great resilience to drought conditions. Valued for its substantial essential oil content and vigorous growth, it serves well in borders, naturalistic settings, and gardens aimed at attracting pollinators.
