Eupatorium fistulosum - 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.
