BONESET (Eupatorium perfoliatum)
Joe-pye weed-esque, but with white fluffy flowers. I love this plant because I think it has the coolest leaves – each pair of opposing leaves is joined at the stem, making it look like a single leaf has been pierced by the stem (right photo). Though notoriously bitter, boneset is known to provide relief from achy fevers. Ranked S3, vulnerable, in Manitoba.
Grows with flat-topped goldenrod, panicled aster, joe-pye weed, tall meadowrue, prairie loosestrife, bog muhly, and fowl manna grass.
