Common Feverfew

Common Feverfew (<em>Tanacetum parthenium</em>) is a flowering herbaceous plant belonging to the genus Tanacetum within the family Asteraceae. It is characterised by its aromatic foliage and clusters of small daisy-like flowers with white ray petals surrounding yellow disc florets. The species typically inhabits Mediterranean forests and woodlands within the Palearctic biogeographic realm, and is also often found in disturbed habitats, roadsides, walls, and garden margins. Its geographic range is exceptionally wide, spanning Asia including Cyprus, India, and Japan, 27 European countries, North America including Canada, Mexico, and the United States, Australia, and multiple South American countries. <em>Tanacetum parthenium</em> is assessed as Least Concern on the IUCN Red List. The plant has a long history of medicinal use, particularly in the treatment of migraines and fevers, from which its common name derives. Biological traits including average lifespan and detailed ecological data remain poorly documented in the scientific literature, though it typically grows as a short-lived perennial or biennial.
