Tansy (''Tanacetum vulgare'') is a perennial, herbaceous flowering plant in the genus ''Tanacetum'' in the aster family, native to temperate Europe and Asia.

Common names include ragwort, common ragwort, stinking willie, tansy ragwort, benweed, St. James-wort, stinking nanny/ninny/willy, staggerwort, dog standard, cankerwort, stammerwort. In the western United States it is generally known as tansy ragwort, or tansy, though its resemblance to the true tansy is superficial. In some countries it is an invasive species and regarded as a noxious weed. In the UK, where it is native, it is often unwanted because of its toxic effect for cattle and horses, but it is also valued for its nectar production which feeds insect pollinators and its ecological importance is thus considered significant. Description The plant is generally considered to be biennial but it has the tendency to exhibit perennial properties under ...
