Fam:   Asteraceae (Compositae)
Genus:   Achillea L.
English Name: Yarrows

Description:

Perennial herbaceous plants, usually developing rhizomes, often more or less fibrous. Stems single to numerous, erect, rarely ascending or recumbent. Leaves consecutive, herbaceous, entire, simple or double to quadrupole feathery divided, on petioles or sessile. Baskets heterogamous, rarely homogemous, back ovoid, small, most often with a small number of flowers, collected by many in apical thyroid complex inflorescences or hemispherical, large, single at the tips of stems and twigs, with many flowers to up to few, usually on short, less often elongated petioles. Enveloping leaflets in several rows, slightly unequal, in part tiled overlapping, more or less membranous at the edge; the outer ones shorter and narrower than the middle and inner ones. Flower bed convex, hemispherical to conical, rarely flat, with lance or oblong hemi membranous, deciduous bracts. Flowers uniformly or unevenly colored; external tongue, female, white, pink, reddish or yellow; tongues at the tip 3-teeth, usually spreading, rarely short, erect; inner flowers bisexual, tubular, yellow or pink, the wreath at the tip 5-toothed, partly flattened along the length, narrowly tubular at the base, elongated, rarely dilated, covering the tip of the fruit seed. Anthers linear, basically without appendages. The style with linear, thin shares. Fruits uniform, oblong-wedge-shaped to oblong-ovate or oblong, gray-brown, truncated at the apex, more or less winged at the edge, almost flattened, without secretory or mucous cells. The kite is missing. Insect-pollinated plants; propagated by seeds and rhizome shoots.

Economic significance. The above-ground parts of most species contain essential oil with the main ingredients chamazulene, terpenes, sesquiterpene lactones, tannins. The species from the group of A. millefolium are recommended for liver diseases, as well as for inflammatory diseases of the kidneys and urinary tract. The drug and its products have a hemostatic and anti-inflammatory effect. A. crithmifolia and A. clypeolata are also used in folk medicine (Petkov, ed. 1982; Nikolov, ed., 2006)

Achillea /ækɪˈliːə/[3] is a group of flowering plants in the family Asteraceae, known colloquially as yarrows. They were described as a genus by Linnaeus in 1753.[4][5] The genus was named after the Greek mythological character Achilles. According to legend, Achilles' soldiers used yarrow to treat their wounds,[6] hence some of its common names such as allheal and bloodwort.
The genus is native primarily to Europe, temperate areas of Asia, and North America.[7][8] The common name "yarrow" is usually applied to Achillea millefolium,[9] but may also be used for other species within the genus.

Description

These plants typically have frilly, hairy, aromatic leaves. The plants show large, flat clusters of small flowers at the top of the stem. The flowers can be white, yellow, orange, pink or red and are generally visited by many insects, and are thus characterised by a generalised pollination system.[10]

Ecology

Achillea species are used as food plants by the larvae of some Lepidoptera species - see list of Lepidoptera that feed on Achillea.
