Tansy (Tanacetum vulgare) is a perennial, herbaceous flowering plant of the aster family, native to temperate Europe and Asia. It has been introduced to other parts of the world, including North America, and in some areas has become invasive. It is also known as common tansy, bitter buttons, cow bitter, or golden buttons. The Latin word vulgare means "common".
From Old French tanesie, tanoisie et al., aphetic form of athanasie, from Medieval Latin athanasia, from Ancient Greek ἀθανασία (athanasía, “immortality”). Doublet of athanasy. Alternatively, from a Vulgar Latin tanacita, possibly from *tanacetum, composed of thannus and acetum (see Rey 2013, Dictionnaire de la langue française, page 2386).
