Campsis radicans.

It can be a very aggressive spreader, with suckers popping up yards away, so you may want to consider removing entirely.

In addition to the above, it will grow and bloom best if in more sun.

Thanks for identifying this vine for me. I recognize it now. It's growth is so spindly it never occurred to me it was a trumpet vine. Here in SW Nebraska, they don't grow well at all, and never put out sucker shoots, so I believe I will move it into the sunshine. But I know what you mean about being invasive from living in Oklahoma where it grew wild.
