- Description
-
Eutrochium dubium, or Coastal Plain Joe Pye Weed, recently moved from the genus Eupatorium, is a herbaceous flowering perennial in the Asteraceae (daisy) family and is native to the eastern coastal plains and wetlands of North America. While it grows rather tall, dwarf varieties exist for use in smaller spaces.
The plant grows easily in a variety of soils from moist, fertile, and humusy to sandy or gravelly and in full sun to part shade. It will not tolerate full shade or dry soil. Also, the leaves may scorch if the soil is allowed to dry out. Light pink to dark purple flowers appear in summer and last through early fall. The flowers attract butterflies and the seeds provide food for songbirds. You can cut the plant back to the ground in winter and it will rebound in spring. Note also that the plant spreads by self-seeding.
Diseases, Insects, and Other Plant Problems: No known serious insect or disease problems. Good resistance to powdery mildew.
