Eupatorium fistulosum
Joe Pye weed or hollow stemmed Joe Pye weed
Joe Pye Weed is a robust, upright perennial with hollow purple stems accented by huge, rounded, tight clusters of pink or purplish-mauve flowers. It is an important pollen and nectar plant and attracts butterflies (particularly the swallowtail butterfly) and other pollinaters by the dozens. The height of Joe Pye Weed makes it an excellent backround plant in border perennial beds, but is also majestic standing alone. Flower color is darker in cooler weather.

Interesting Notes
The genus Eupatorium is after Mithridates VI Eupator (c. 120-63 BC) the most powerful king of Pontus, who may have used a plant in the genus as a remedy or perhaps an antidote as he was known to have ingested small amounts of many types of poison in order to attain immunity. The species name 'fistulosum' refers to the hollow stem. The Joe Pye of the common name is that of a character in 19th-century New England who may have been a Native American healer (real name Zhopai?) or a white promoter of Indian themes. At any rate he is credited with using Joe-Pye Weed to cure settlers of typhus by sweating them. 2bnthewild.com
