PA to MN, south to northern FL and TX. | |
| Abundance | Uncommon to infrequent in the southern Mountains; rare in the southwestern Piedmont. | |
| Habitat | Dry and open pine-deciduous woodlands, edges and openings, rocky slopes, roadside banks, fields. A species of sunny to partly sunny places. | |
| Phenology | Flowering and fruiting July-October. | |
| Identification | Plants typically grow 2-5 (-6) feet tall from long rhizomes, the stems coarsely hairy throughout. Leaves are opposite, short-stalked, lance-shaped to ovate, up to 6 inches long and 3 inches wide, coarsely hairy on both sides (may be scabrous above). Rays and disks are yellow. Together, the long rhizomes (greater than 4 inches) and long hairy stems and leaves should clinch identification. The non-native (in NC) Ashy Sunflower (H. mollis) has soft-hairy leaves. At first glance, this species looks like the much more common H. divaricatus, but that species has a smooth stem as opposed to a clearly hairy stem. | |
