Bright snowy white, double flowers measuring about ½" across blanket this yarrow in dense clusters from early summer well into fall. The plant forms a neat, dome-shaped mound that stays compact, making it ideal for the front of sunny borders where space is limited. Exceptionally drought tolerant once established, it flourishes in well-drained soil and shrugs off heat with ease. Pollinators flock to the long-lasting blooms, while deer tend to leave it alone, ensuring reliable colour with minimal upkeep.
