Echinacea tennesseensis

Native to only a handful of counties in Tennessee, Echinacea tennesseensis is a conservation success story. Once a federally endangered plant, concerted conservation efforts resulted in its delisting as an endangered species in 2011.  Our trial included the straight species and the widely grown cultivar Echinacea tennesseensis ‘Rocky Top’, both of which performed similarly. A unique feature of this species is its predominately eastward-facing flowers that feature attractive upturned petals. The drought tolerance of the species is well documented in its natural habitat, and the floppy habits observed in the trial could be mitigated in leaner soils.
