Description & Identification

This plant is visually distinctive due to its fused leaves, and as such is easily distinguished from other similar-looking species.


Found primarily on wetland margins, including shores of lakes and rivers, or margins of marshes or swamps. Also found in sunny openings in floodplains, poorly-drained areas in wet prairies. Also found in wet anthropogenic habitats, including roadside ditches and drainage ponds.


Common boneset is sometimes used as a garden or landscaping plant, particularly in native plant gardens. Can be grown on drier ground than it would naturally occur, but plants can become stressed in dry weather.

There are numerous other Eupatorium sp. with overlapping ranges in most parts of this plant's range. In addition, there are plants of other genera in the Eupatorium tribe, also closely related.
