Artemisia is a genus of aromatic herbs that includes wormwood, mugwort, and tarragon — plants with a history stretching back thousands of years across medicine, ritual, and cuisine. In perfumery it contributes a sharp, green, slightly bitter quality that sits somewhere between herb and forest — wild rather than cultivated, unsettling rather than comforting. It is the note that stops a fragrance from being too easy, too polished, too safe. Used with restraint it adds a restless, almost feral intelligence to a composition. Davana, one of perfumery’s most shape-shifting ingredients, belongs to the same family — which tells you everything about the range and complexity that the artemisia genus brings to the palette.
