Achillea is a genus of flowering plants, commonly referred to as yarrow, that are frequently used in garden borders and beds in ornamental horticulture. These plants typically have frilly, hairy, aromatic leaves and flat clusters of small flowers at the top of the stem. The flowers themselves may be small, but the clusters are usually both large and showy. Achilleas have an unusually long flowering period for temperate perennial plants, and most species also have an attractive architectural form. These traits, along with disease and drought resistance, have been combined in strains domesticated as garden plants. Many of these varieties are commercially cultivated and available in nurseries. Such selections offer a range of color in both foliage and flower, and a variety of forms and heights that all have uses in garden design. Achillea species are versatile plants that have uses in both informal and formal ornamental gardens.

In their wild form, they are native to Europe and temperate areas of Asia. A few grow in North America. Several forms of wild Achillea have been used as medicinal herbs.

The genus was named for the Greek mythological character Achilles. According to the Iliad, Achilles' soldiers used yarrow to treat wounds [1], hence some of its common names such as allheal and bloodwort.

Achillea species are used as food plants by the larvae of some Lepidoptera species - see list of Lepidoptera which feed on Achillea. As an attractant for butterflies, they add yet another dimension to the ornamental garden.

Garden Hybrids

Achilleas are themselves attractive in an ornamental garden, and reliably add the presence of butterflies to flower gardens in temperate regions. This aspect of the plant's effectiveness can be amplified by the addition of other mainstays of butterfly gardening, like buddleia (butterfy bush), salvia species, and ageratum, and by the avoidance of pesticides that are harmful or fatal to the butterflies.


Achilleas are, as a group, drought resistant plants that require full sun and good drainage in order to thrive.
