Dicentra or Corydalis?

Thanks. Interesting idea, dicentra. I have many Dicentra eximia wandering around, seeding themselves, though some distance from this spot. But the pictures on Google show an even more finely cut leaf for dicentra than this, see the link below, although the plant in my picture is a young one. And dicentras do form a whorl about a central root as the plant in my picture does. Maybe that's it (can't actually do the comparison now, the plant is up in the "country.") Don't know corydalis at all, but will look it up.

Tall Meadow Rue, maybe? Thalictrum pubescens.

I've also got some meadow rue around (I think the same species), so that's a possibility as well. I can do a further examination over the week-end and compare with both that and the dicentra. My picture's a little fuzzy unfortunately, so the exact leaf or leaflet form isn't clear.

Thanks for the suggestions. Anybody else?

That's Adlumia fungosa without a doubt. Don't try to move it, give it something to grow on if possible.

Just wanted to give credit to jeanne. It was indeed Adlumia fungosa, although it took a while for me to be sure.

Isn't it the neatest thing? Mine has been blooming for a couple of weeks and is already approaching 12 feet, just found it's way over the Philadelphus. It looks like it's going to be a very good year for the Allegheny Vine.
