Add a splash of colour to your summer flower garden or border for years to come with this pretty perennial. Terracotta's flat-topped flower heads, or corymbs, reach 3-4" in diameter and are packed with tiny florets resembling daisies. These small but fragrant blooms start out salmon-pink and turn yellow-orange as they mature. An excellent choice for use as a cut flower, whether fresh or dried.Achillea millefolium
