Broad-leaved tickseed is a slender, erect, perennial herb that grows in rich sandy-loams of the Blue Ridge Mountains. It is found in and around the Black Mountains and along the Blue Ridge Escarpment from the Craggies to the South Carolina line with disjunct populations in Tennessee (Sutter 1989). The plant often grows to 1.5 meters in length and is essentially glabrous with long rhizomes. The inflorescence is a small corymb with yellow ray and disk flowers (Radford 1968). From August to September, yellow flowers develop that will produce 10-15 seeds per head. Many of this specie's populations now appear stable (Sutter 1989).
