24-7-2025 FOTA WILDLIFE PARK COBH, IRELAND - COMMON YARROW (Achillea millefolium)

Achillea millefolium, commonly known as yarrow (/ˈjæroʊ/) or common yarrow, is a flowering plant in the family Asteraceae. Growing to 1 metre (3+1⁄2 feet) tall, it is characterized by small whitish flowers, a tall stem of fernlike leaves, and a pungent odor.

The plant is native to temperate regions of the Northern Hemisphere in Asia, Europe, and North America. It has been introduced as a feed for livestock in New Zealand and Australia. Used by some animals, the plant may have somewhat toxic properties, although historically it has been employed for medicinal purposes.

Achillea millefolium is an erect, herbaceous, perennial plant that produces one to several stems 0.2–1 metre (8–40 inches) in height, and has a spreading rhizomatous growth form. Cauline and more or less clasping, the leaves appear spirally and evenly along the stem, with the largest and most petiolate towards the base; they are 5–20 centimetres (2–8 in) long and fernlike, divided bipinnately or tripinnately.

Achillea millefolium is an erect, herbaceous, perennial plant that produces one to several stems 0.2–1 metre (8–40 inches) in height, and has a spreading rhizomatous growth form. Cauline and more or less clasping,[2] the leaves appear spirally and evenly along the stem, with the largest and most petiolate towards the base; they are 5–20 centimetres (2–8 in) long and fernlike, divided bipinnately or tripinnately.

The inflorescence has 4 to 9 phyllaries and contains ray and disk flowers which are whit to pink, blooming from March to October There are generally 3 to 8 ray flowers, which are 3 millimetres (1⁄8 in) long and ovate to round. The tiny disk flowers range from 10 to 40.[5] The inflorescence is produced in a flat-topped capitulum cluster and the inflorescences are visited by many insects, featuring a generalized pollination system. The small achene-like fruits are called cypsela.

The plant has a sweet scent similar to that of chrysanthemums, so powerful that it may be irritating to some.

The dark blue essential oil of yarrow contains chemicals called proazulenes.

Chamazulene and δ-Cadinol are chemical compounds found in A. millefolium. The chromophore of azulene was discovered in yarrow and wormwood and named in 1863 by Septimus Piesse.

Yarrow contains isovaleric acid, salicylic acid, asparagine, sterols, and flavonoids. It also contains phenolic acids such as gallic acid, 3, 4-dihydroxy benzoic acid, chlorogenic acid, vanillic acid, caffeic acid, syringic acid, p-coumaric acid, sinapic acid, ferulic acid, cinnamic acid and flavonoid such as myricetin, hesperidin, quercetin, luteolin, kaempferol, apigenin, rutin, hyperoside.

Yarrow is native to temperate regions of the Northern Hemisphere in Asia, Europe, and North America.

The plant grows from sea level to 3,500 m (11,500 ft) in elevation. Common yarrow is frequently found in the mildly disturbed soil of grasslands and open forests. Active growth occurs in the spring.

It has been introduced as a feed for livestock in New Zealand and Australia, where it is a common weed of both wet and dry areas, such as roadsides, meadows, fields and coastal places.
