Achillea coarctata 'Moonshine'
Classic, clumping, yellow-flowered yarrow, 18-24” tall and as wide, with silvery-hairy leaves. A more uniform and well-behaved Yarrow, this is a favorite for borders or neat, meadow-style gardens. Blooms for a long time starting in early summer, and will re-bloom into fall if cut back after the first flowering. Deer-resistant. Like poor to average, dry soil and full sun. Zones 3-8.
