A beautiful native plant of damp places; occasional in open sunny moist places in the Park, especially in Connelly's Run floodplain.

Sometimes confused with New York Ironweed (Vernonia noveboracensis), but that plant has deep violet flowers which are much larger and in looser clusters, and leaves not in whorls.  Sweet-scented Joe-Pye Weed grows in the woods of Wildwood.  It has pale pink, almost white flowers, wider leaves, and sharper teeth.  Bonesets, also in the genus Eupatorium, are somewhat similar, but have white flowers and leaves in pairs.
