Q.Wisteria Survival
About 5 years ago we planted a wisteria about 20’ from a trumpet vine. It never blossomed but this year we had orange trumpet flowers among the lush vines. Not being able to adequately distinguish trumpet leaves from wisteria, I trimmed it back to the trunk (photo). Our zone in upstate NY is 6a. Will it survive and what do you think it is?

It will survive, but I can't say without a doubt that this is Wisteria. This could, very well, be Campsis. Whichever it is, you will need to let it re-grow in order to know for sure.
Either species will come back, easily, after a hard prune.
