For common tansy there are only 6 Watershed locations: 5 miles W of San Luis (Costilla Co); 7 miles SW of Alamosa (Alamosa Co); 1 mile E of South Fork (Rio Grande Co); Fox Creek and FSR 103 (Conejos Co); SW of Creede (Mineral Co). Tanacetum vulgare is a cultivated ornamental that sometimes escapes and nativizes. It is on Colorado's B list of "noxious weeds." It has been observed in all USA states except Texas, Alabama, South Carolina, and Florida. It follows the Rio Grande drainage down to Bernalillo Co, New Mexico.
