Hollow Joe Pye Weed (Eutrochium fistulosum) vs. Sweetscented Joe Pye Weed (Eutrochium purpureum)

Updated September 11th, 2024

These species are frequently confused where their ranges overlap in the eastern and lower Midwestern U.S. Although they can occur relatively near each other on the same site, they have mostly non-overlapping habitat preferences. They can usually be distinguished by characteristics of their stem, and often also by their height, inflorescence shape, and number of leaves per whorl. E. purpureum ranges farther north and northwest, and occurs in drier, shadier, better-drained habitats. E. fistulosum ranges farther south and prefers moister, sunnier, more disturbed habitats, and is more tolerant of flooding and waterlogged soils.

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

Updated September 2nd, 2024

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 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.

Hollow Joe Pye Weed (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.
