Achillea millefolium, Achillea filipendula, Achillea ptarmica
Drought tolerant and tough, Yarrow is rarely eaten by deer and rabbits which makes it a great choice for massing in borders or along the edges of wooded or wild places. Achillea millefolium, commonly known as yarrow /ˈjæroʊ/ or common yarrow, is a flowering plant in the family Asteraceae. It is native to temperate regions of the Northern Hemisphere in Asia, Europe, and North America. Yarrow is a hardy and versatile perennial with fernlike leaves and colorful blooms. The large, flat-topped flower clusters are perfect for cutting and drying. Most yarrows grow 2 to 4 feet tall, although low-growing varieties are also available. The plants are remarkably durable, tolerating dry spells and low soil fertility where other perennials would fade. Yarrows bloom from midsummer into fall; flower colors include red, pink, salmon, yellow, and white. Yarrow are versatile and look equally at home in a perennial border, sunny rock garden, or wildflower meadow. Powdery mildew disease may be a problem in humid areas. Common Yarrow is widely adapted and tolerates both heat and poor soil. Winter hardy to zone 3.
