What do you think of this for minnesotas weather, i never even planted it, it seeded itself...and took over my angel...
Here is a link that might be useful: trumpit vine
I think the plant you're referring to might be datura...it does have trumpet-shaped flowers though I don't believe it's a vine. Be careful of that one, there's been a rise in kids going to the emergency room because of it.
trumpet vine, aka Campsis radicans
datura, aka Datura spp.
