"Eupatorium fistulosum" ("Eutrochium fistulosum" (Barratt) E. E. Lamont), also called Joe-Pye weed, Trumpetweed, or Purple thoroughwort, is a flowering plant in the family Asteraceae, native to eastern North America, in southeast Canada and throughout the eastern and central United States.

It is a herbaceous perennial plant growing to 1.5-3 m (5-10 feet) tall, found in moist, rich soil alongside ditches and marshes, or in wet forests. It flowers from mid-summer to the first frosts, makes an attractive backdrop in garden plots, and is very attractive to butterflies, bees, and other nectar-feeding insects. (See also Eupatorium.)

The plant has one simple erect stem, which is green with purple dots or longitudinal dashes. The upper stems are reddish or purplish. Leaves appear in whorls of 3-5. Leaves are large, long and sharply toothed.
