* Carduus Report on ITIS
Carduus is a genus of about 90 species of thistles in the family Asteraceae, native to Europe, Asia and Africa. Carduus is Latin for a thistle.
Carduus thistles are used as food plants by the caterpillars of some Lepidoptera species, including the Thistle Ermine (Myelois circumvoluta) and the case-bearer Coleophora therinella.
* Carduus acanthoides (Plumeless Thistle)
* Carduus × orthocephalus
Cardonnacum, derived from carduus, is Latin for a place with thistles. This is believed to be the origin for the name of the Burgundy village of Chardonnay, Saône-et-Loire, which in turn is thought to be the home of the famous Chardonnay grape variety.
