Vegetative characteristics

The Achillea species are perennial herbaceous plants , rarely sub-shrubs that reach heights of 6 to 80 centimeters. The whole plant usually smells aromatic. In spring, the rhizome sprouts a rosette of leaves. Later, a stem grows on which the flowers form. The smooth to hairy stem is tough and marrow-bearing inside.

The alternate leaves are stalked to sessile. The leaf blades are narrow and pinnate.

Generative characteristics

The simple or compound shawny inflorescence consists of many small cup-shaped partial inflorescences . 10 to 30 bracts are in (one to) two to three (up to four) rows. The flower heads usually have a diameter of 2 to 3 (rarely 5) millimeters and contain (5 to) 15 to more than 75 tubular and rarely none, but mostly three to five (up to twelve or rarely more) ray-flowers . The color of the ray florets of most species is white to pale yellow, pink tints also occur.

The achenes usually have two ribs.

Systematics and distribution

The genus Achillea was established by Carl von Linné . The botanical genus name Achillea is derived from the Greek hero Achilles , who, according to legend, was once said to have treated his wounds with the help of this plant. Synonyms for Achillea L. are: Leucocyclus Boiss. , Ptarmica Hill

The Achillea species are native to the subtropical to temperate zone of Eurasia , but some species are also found in North Africa and America. They are native to all of Europe up to the Arctic Circle and also in the Alps.

There are 115 to 200 species in the genus Achillea (selection):

use

The blooming yarrow is used as a bitter tonic for digestive disorders and colic. The flowers are also used to care for facial skin in steam baths. The fresh shoots and leaves can also be used as an addition to salads and the essential oils have an expectorant effect.

Chopsticks for the traditional Chinese yarrow oracle were made from the stems , see also I Ching .
