PhenologyFlowering and fruiting late July-October.
IdentificationThis is our tallest joe-pye-weed, usually 6-9 feet, the stems hollow, and has leaves in whorls of 5-7. Thus, it is the easiest to identify. Leaves are lance-shaped, narrowed to both ends, and 6-10 inches long. Inflorescences are large and irregularly dome-shaped. The heads are pink or reddish pink. This is the state's most common or widespread member of the genus, very familiar and striking when in bloom, especially when butterflies such as swallowtails converge on the inflorescence.
Taxonomic CommentsFormerly treated as Eupatorium fistulosum.
