Does anyone recognize this?? It started growing in the wildflower bed last spring. I thought it was pretty, so I just let it go. It adds quite a bit of texture and interest to that bed, but over the summer it has gotten way out of hand.

It has very fine, fern like branches. I promise-I did not plant it. Hubby thinks I must have just forgotten that I planted it, but I think I would remember..wouldn't I? It's not like I have anything else on my mind, right? :)

I will be ready to plant wildflower seeds in about a week, so I will need to cut this back. We are thinking we might try and move it to the corner of the bed this winter, but before I do, I sure would like to know what it is!
Can somebody out there please help me??
