This could be *Vernonia arborea*.
Yes even i guess Vernonia, (may be V. acuminata, pls check correct name for the same)
My photos are all low-light-long shots making it difficult for all of us to ID.

Requesting id: observed this flowering herb/ shrub in full bloom, attracting variety of butterflies. Couldn't zero on species.
Is it Vernonia? I think this can otherwise be Centratherum sp. (may be C. anthelminticum).
