Diagnostic Characteristics:
Spreading false foxglove is perennial which distinguishes it from A. pedicularia, a species of dry woods. It is pubescent throughout the inflorescence but none of these hairs are glandular. It typically occurs associated with limestone substrates along the slopes of larger streams and rivers.

Degradation of the cliffline above this species could detrimentally affect this plant by causing erosion and weed invasion. Changes in hydrology caused by overstory removal (along the bluffs above the river slopes/cliffs), road/trail construction could be detrimental. Excessive erosion at the base of the cliffs along the impoundment could also undermine the habitat for this species. Exotic pest plants are a threat to this species.

Global Range:
Central Kentucky, northern Georgia to Tennessee. Edmonson, Pulaski, and McCreary counties, Kentucky; Rome, Georgia; Roane, Knox, Loudon, Morgan, Coffee, and Montgomery coutnies, Tennessee.
