Achillea, commonly known as yarrow, is a hardy perennial valued for its feathery, fern-like foliage and long-lasting clusters of flat-topped flowers that bloom from late spring through summer. Thriving in full sun with well-drained soil, yarrow is drought-tolerant, low-maintenance, and attracts pollinators like bees and butterflies. Available in a variety of colors from white to yellow, pink, and red, yarrow brings texture, seasonal color, and versatility to perennial gardens, borders, and cottage landscapes.
