This plant appeared this spring and is already about 3 feet high and several feet across. Given the opposite compound leaves, Campsis radicans is the closest match Iíve found, though I would appreciate confirmation or other suggestions.
SOLVED: Is this a trumpet vine?
Not trumpet vine (Campsis radicans).
Looks more like a Bidens. If it is, it should be getting close to setting some flower buds. Maybe others will chime in.
Agree with Bidens sp... except for part of one compound leaf in upper right of first picture.
That looks like something different than that main plant in the center of the picture.
Show us more of THAT...
