Achillea tolerates a wide range of soil and conditions but prefers an open sunny site and moist but well-drained soil.
“This species was cultivated in Europe before 1440, used as a remedy for toothache, and mixed in ale in place of hops to increase the inebriating quality of the drink. […]. The main use, however, was that of an herb to heal wounds. The genus was named after Achilles, who is said to have used A. millefollium to staunch the wounds of his soldiers. Soldier’s Woundweed and Carpenter’s Weed are other old English names.” – Allan Armitage
