About
Eutrochium fistulosum (Eupatorium fistulosum), also called hollow Joe-Pye weed, trumpetweed, or purple thoroughwort, is a perennial North American flowering plant in the family Asteraceae. It is native to southern Canada and throughout the eastern and south central United States from Maine west to Ontario, Wisconsin, and Missouri and south as far as Florida and Texas. The specific name fistulosum refers to the tubular stem; see fistula.
Eutrochium fistulosum is a herbaceous perennial plant sometimes as much as 350 cm (140 in; 11 ft 6 in) tall. It is 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.
