Genus: Echinacea

Echinacea Moench, Methodus, 591. 1794.List of Echinacea Species
General Discussion
Echinacea pallida (Nutt.) Nutt. and Echinacea purpurea (L.) Moench, both native from the midwestern to southeastern 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, therefore these two species are excluded from our flora.
