Trumpetweed (Eutrochium fistulosum) vs. Spotted Joe Pye Weed (Eutrochium maculatum)

Updated September 25th, 2020

These two species are sometimes confused in the northeast where their ranges overlap broadly; both are found in wet, sunny habitats. They are usually easily distinguished by a variety of attributes, including stems, inflorescence color and shape, plant height, and number of leaves per whorl. E. maculatum is more likely to be found in intact natural wetlands with mineral-rich soils, whereas E. fistulosum is more likely in disturbed or degraded habitats.

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.
