Eutrochium dubium,[2] also called coastal plain joe pye weed, is a North American flowering plant in the family Asteraceae. It is native to the eastern United States and Canada, primarily the Atlantic coastal plain from Georgia to Nova Scotia.[3]

Eutrochium dubium is a herbaceous perennial plant herb sometimes as much as 170 cm (68 inches or 5 2/3 feet) tall. Stems are sometimes purple, sometimes green with purple spots. The plant produces numerous flower heads in flat-topped arrays, each head has 4-10 dark purple (rarely pink or white) disc florets but no ray florets.[4] The flowers are attractive to birds.[5]

Eutrochium dubium prefers full sun to part shade. It will grow in a variety of soil types, provided the soil does not dry out.[6]
