Achillea millefolium, commonly known as Yarrow, is a hardy, adaptable perennial native to temperate regions across the Northern Hemisphere. It is easily recognized by its soft, feathery foliage topped with large clusters small, tightly packed flowers. Blooming continuously from early summer through early autumn, it produces blossoms in shades of white and cream in the wild, though cultivated varieties offer rich hues of red, pink, yellow, and deep orange. Its fine, deeply segmented leaves emit a pleasant, spicy herb fragrance when crushed.
