The greatest threat facing the Tennessee purple coneflower is destruction or alteration of its habitat as a result of commercial, residential, or industrial development, road-building, intensive livestock grazing, encroaching vegetation, and off-road vehicle use (7). Over-collection for the plant’s ornamental and perceived medicinal qualities poses an additional threat (4). Although there are many suitable glades in Middle Tennessee, this plant appears to be restricted to just a few due to its poor colonisation ability. Being shade intolerant means that it is difficult for the Tennessee purple coneflower to get past the tree-lined margins of the glades. It is also restricted by being self-sterile and reliant on other plants to reproduce (6). Thus, the Tennessee purple coneflower’s limited ability to colonise new areas makes the protection of its current sites all that more important (4).
