Coastal Plain Joe Pye Weed (Eutrochium dubium) vs. Spotted Joe Pye Weed (Eutrochium maculatum)

Updated September 21st, 2020

These species are easily confused where their ranges overlap, from southern New England through New Jersey. Both inhabit wetlands, have spotted stems, and can be on the shorter side among Joe Pye weeds. However, they are usually easily distinguished by inflorescence shape, number of florets per head, and leaf vein pattern, and sometimes bloom color or number of leaves per whorl. E. dubium prefers more acidic habitats, whereas E. maculatum prefers more mineral-rich soil.

Coastal Plain Joe Pye Weed (Eutrochium dubium) vs. Trumpetweed (Eutrochium fistulosum)

Updated September 19th, 2020

These 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 limited to moist, acidic soil, mostly coastally, whereas E. fistulosum inhabits a broader range of wet, disturbed areas and is more common farther inland.
