| Distribution | Throughout the state, but absent from the Sandhills proper (and several adjacent counties) and from most barrier islands.
N.S. to Man., south to northern FL and TX. | |
| Abundance | Frequent to common in the Mountains, the central and northern Piedmont, and most of the Coastal Plain. Absent in the Sandhills proper, and curiously scarce in the southeastern Piedmont. | |
| Habitat | Freshwater marshes, openings in floodplain forests and maple-gum swamps, wet pastures, damp meadows, montane seepage bogs. |
| Phenology | Flowering and fruiting August-October. | |
| Identification | This robust wetland plant typically reaches 3-4 feet tall, with long, pointed leaves that are not only sessile (without stalks) but the bases are joined around the stem. This "suturing" of the leaves gives rise to the fanciful notion of repairing bone fractures. No other Eupatorium has leaves like this, making this perhaps the easiest to identify of the state's 28 species in the genus. | |
