Hello and welcome! Come 'play' with us in the Texas forum. :)
Since I'm using my phone right now it's hard to look at pictures on the phones tiny screen. I'll take a better look when I get over to my desktop.
Are the little flowers part of the plant in question or just on a plant next to it?
Lin put your question on the Texas forum (thanks, Lin) so maybe someone there will wake up and ID your plant.
stone is usually good at identifying plants. If it is Boneset then I think it would have white flowers and not what I think I'm seeing. So anyway, I'm in Dallas and a lot of people in the general area grow Boneset. And I've seen it at my 2 favorite nurseries here.
Don't pull it until we can ID it.
