| Distribution | In widely scattered locations across most of the state, from low elevation Mountains to the Piedmont to the northern Coastal Plain. The gaps in the range are real, though (of course) it likely can and will be found eventually in other counties within the large gaps.
VA to IL and MO, south to northern FL and TX. | |
| Abundance | Very rare to rare, to locally uncommon in the Brushy Mountains (Wilkes and Alexander counties). This is a Significantly Rare species. | |
| Habitat | Dry to moist, nutrient-rich or mineral-rich soils over mafic or limey rock, within hardwood forests or pine-hardwoods, or rarely brownwater river bottomlands. Most sites in the Brushy Mountains are on granitic domes, where mafic minerals are embedded in the granite. The species is strictly found in high pH soils. | |
| Phenology | Flowering and fruiting late August-October. | |
| Identification | Pink Thoroughwort is rarely seen in NC, even by the most energetic botanists. It is difficult to predict where one may find a population, as most apparently suitable sites lack it. It is very distinct, however, with its lazy stems (sometimes weakly climbing), paired, ovate to triangular and pointy leaves (with truncate bases), and heads of pink disk florets. The heads are produced on stalks from leaf axils along the upper portion of the plant. | |
| Taxonomic Comments | Formerly treated as Eupatorium incarnatum.
