Facts About

Fetid-marigold is a native of the Central United States, and is probably ephemeral in the Northeast. The potential to live up to its common name was noted by C. W. Short in 1837: "This plant is so abundant, and exhales an odor so unpleasant as to sicken the traveler over the western prairies of Illinois, in autumn."
