Watch for Boneset (Eupatorium perfoliatum) blooming now in western Pennsylvania.

Boneset’s common name comes from the old-time theory that boneset’s joined leaves meant it would heal broken bones.  Its scientific name, perfoliatum, also refers to the joined leaves which are perforated by the plant stem, as shown above.

If you haven’t seen boneset blooming yet, you can find it at Jennings Prairie.
