Tansy is a small plant with bright yellow flowers and a spicy smell (scientific name, Tanacetum vulgare sunflower family, Asteraceae). It is native to western Asia but long ago became an herb and spice that was grown throughout Europe and then transported by Europeans all over the world. Today we know it more as a garden flower or roadside weed than as a flavoring or medicine, but it is all of those.
