It is a native vine, Campsis radicans - Trumpet Creeper. It can be aggressive, yes.

Thank you so much. I'm trying to figure out what to keep in this abandoned garden and what needs to go. That trumpet creeper sure is pretty but you're right, "aggressive" is an understatement. It is busy trying to cover every paved area, who knows what is doing up on the hillside. Oh my.......I am going to be busy.

Thanks for the ID!!!
