Coastal Plain Joe Pye Weed (Eutrochium dubium) vs. Trumpetweed (Eutrochium fistulosum)
Updated September 2nd, 2024These plants are sometimes confused where their ranges overlap in southern New England through the Mid-Atlantic. They are easily distinguished by their stems and leaf vein pattern, and often also by height or number of leaves per whorl. E. dubium is slightly more tolerant of shade and drier conditions, prefers less-disturbed habitats, and is limited to acidic soil, mostly near the coast. E. fistulosum requires more nutrient-rich soil and sun, favors more disturbed areas, and is more common farther inland.
