location ;... indoors or out.. and an in focus pic would help

ken

Outdoor perennial. Hardy. Flowers just whited out in my photos. They are small, just 1/4" or so, the 'petals' are like thin white filaments.

What about something like Eupatorium (joe-pye weed) Chocolate?

Having a photo of the whole plant as well as closeup(s) that show flowers, leaves, and branching is helpful.

Yes, I think that is it, Eupatorium Chocolate, thanks so much NHBabs!
