Ratibida Rafinesque, Fl. Ludov., 73. 1817.
List of Ratibida Species
Ratibida columnifera (Nutt.) Wooton & Standl. and Ratibida pinnata (Vent.) Barnh., both native to the midwestern United States, have been purported to have been introduced in our area. However, the handful of reports from our area are ambiguous regarding their cultivated status. Further research is needed to determine if these species are truly naturalizing.
