Yarrow is any of a group of plants that typically develop flat clusters of flowers and fernlike leaves. Yarrows grow worldwide in temperate zones—that is, areas between the tropics and the polar regions. Many people consider wild yarrows to be troublesome weeds. However, scientists have created varieties of yarrows that growers use in wildflower gardens.
Yarrows are perennials, which means they live more than two years. The common yarrow may grow about 1 to 31/4 feet (30 to 100 centimeters) high. This plant has clusters of tiny white or pink flowers. Its elongated leaves possess many leaflets, giving the plant a fernlike appearance. Yarrows grow best in well-drained soil.
In Greek mythology, the warrior Achilles used yarrow plants to treat his soldiers’ wounds. Native Americans used yarrows to reduce pain and fever.
