| Distribution | Southern half of the Outer Coastal Plain; scarce in the northern portion, north to Martin County.
Coastal Plain, NC to northern FL and southeastern LA. | |
| Abundance | Can be fairly common in well-managed savannas, but uncommon as a whole in the southeastern Coastal Plain. Rare north of southern Craven County (i.e., Croatan National Forest). Until recently, it was on the NCNHP's Watch List. | |
| Habitat | Longleaf Pine-Wiregrass savannas and flatwoods, margins of pocosins, pitcher-plant seepages. |
| Phenology | Flowering and fruiting August-October. | |
| Identification | With its well-developed basal leaves and small, sparse stem leaves, this sunflower looks "scapose" (leafless stem). Heads are few (1-3, maximum of 5) with yellow rays and red-purple or brownish disks. Some plants of Purpledisk Sunflower (H. atrorubens) may look similar, but it is a taller plant (2-5 or 6 feet tall vs. a maximum of 3 feet) and lower leaves are toothed on the margins (vs. smooth or nearly so). This is a characteristic sunflower of well-managed (with fire) pine savannas. | |
