Boneset
Boneset
Boneset, Common (Eupatorium perfoliatum)

Description: Common Boneset are usually less than four feet tall. The opposite leaves are paired and united across the stem. Their scientific name, "per" (through) "foliatum" (leaves), provides one intriguing clue in identifying this plant as the stem appears to penetrate through each pair of leaves (see photograph). The stems remain unbranched, except at the tip of the plant, where multiple branches support many small white flowers. 

Habitat: Usually found in wetter areas of prairies and along water courses.
