Wisteria is considered a noxious weed in Florida. They ask people not to plant it, but they have not banned it outright. Oldtimers here call it "strangler vine". Wisteria will actually kill trees that it entwines both by pressure on the trees and by shading them out. It sends underground runners literally for hundreds of feet. The common wisdom is, "If the neighbor 10 houses down has wisteria, so do you". People have tried to contain it with underground barriers but it never helps. Its a beautiful flower, and it smells heavenly, but its not worth it to me.
