Centaurium erythraea, as depicted in 6th-century Leiden manuscript of Pseudo-Apuleius' Herbarius
Centaurium erythraea is a species of flowering plant in the gentian family known by the names common centaury and European centaury. It is also commonly known as feverfoullie, gentian or centaury.
This is an upright biennial herb which reaches half a meter in height. It grows from a small basal rosette and bolts a leafy, upright stem which may branch. The triangular leaves are arranged oppositely on the stem and the upright inflorescences emerge from the stem and grow parallel to it, sometimes tangling with the foliage. Each inflorescence may contain many flowers. The petite flower is pinkish-lavender and about a centimeter across, flat-faced with yellow anthers. The fruit is a cylindrical capsule.
It flowers from June until September.
This centaury is a widespread plant of Europe (including Scotland, Sweden and Mediterranean countries) and parts of western Asia and northern Africa. It has also naturalised in parts of North America, New Zealand, and eastern Australia, where it is an introduced species. It grows in fields and roadsides.
