AMERICAN BONESET

Eupatorium perfoliatum

American Boneset, Eupatorium perfoliatum, commonly called Boneset, is a large, hairy, clump-forming, native perennial which typically occurs in wet soils in low woods, thickets, stream banks, meadows and prairies. It is a magic herb and often used in the treatment of fevers, colds and a variety of other maladies.

Good size and late bloom for borders, native plant gardens, wildflower gardens, cottage gardens, woodland gardens, rain gardens, or banks of ponds or water gardens. Flat-topped clusters (compound corymbs) of small, fluffy, white flowers appear above the foliage in late summer to fall.  Perfoliate foliage is quite distinctive: the bases of the pairs of wrinkled, opposite, lance-shaped, medium green leaves unite to surround the hairy stems (perfoliatum meaning through the foliage).  All parts of the plant are quite toxic and bitter. Also commonly called Thoroughwort.
