Artemisia vulgaris (Mugwort or Common Wormwoo) is one of several species in the genus Artemisia with names containing mugwort. It is also occasionally known as Felon Herb, Chrysanthemum Weed, Wild Wormwood, or St. John's Plant (not to be confused with St John's wort). It is native to temperate Europe, Asia and northern Africa, but is also present in North America where it is an invasive weed. It is a very common plant growing on nitrogenous soils, like weedy and uncultivated areas, such as waste places and roadsides.
