| Abundance | Rare to uncommon in the Mountains; very rare in the Piedmont. | |
| Habitat | Roadsides, yard weed, mountain ridge, campus weed escaped from plantings. | |
| Phenology | Flowering and fruiting August-October. | |
| Identification | This 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. | |
