Ha Ha -- before the trumpet vine, I had wisteria planted in that same spot and it also did poorly and I moved it to a sunnier location. I did get wisteria starts popping up for a while, but they seem to have been eradicated. My thought was to have a summer vine crawl around the northeastern post of my morning porch, fragrant would be good. I've given up with that idea and have now moved some cimicifuga* to that spot, which will get tall enough for me to lean over for a nice smell, and should do better in this morning-sun only space.
*I realize this plant has changed its name, but I've called it this for years and don't see me changing anytime soon. I forget what its new and improved name is. I wish the powers that be would just settle in with one name and be done with it...
