Gaillardia aristata Pursh and G. pulchella Foug., native from the midwestern to southeastern United States, have been purported to have been introduced in our area. However, there is a suggestion that these local records might represent G. x grandiflora (G. aristata x G. pulchella). Until further research determines which species are adventive in our area, all Gaillardia are herein mapped as one unit.
