AbundanceRare to uncommon in the Mountains; very rare in the Piedmont.
HabitatRoadsides, yard weed, mountain ridge, campus weed escaped from plantings.
PhenologyFlowering and fruiting August-October.
IdentificationThis species is readily identified by a stem 3 feet or more tall, the inflorescence a rather flat-topped array of bright yellow "buttons" (ray florets absent), and fern-like dissected leaves. Even when in full bloom, it has the appearance of a plant still in bud, as the disks are so dense that it looks like the florets have still not yet opened.
