Source? likely to be reintroduced: 

A. cotula is thought to have spread through contaminated seed, forage, or ships ballast. It was intentionally introduced to areas of South America as a medicinal herb and may have been introduced to other regions in the same manner. It may also have been introduced intentionally by confusing it with similar species with desired ornamental, herbal, or other properties. However, with its strong putrid odour it is unlikely that it was intentionally planted as an ornamental.
