So-so hardy. There are hardy varieties (the yellow and blue ones, I believe) that can overwinter outside. Then you have to wrap them a little frost-protectively. But not very much. Mine survived it, but we didn't have a winter here either.
My wife loves wisteria. It loves sun and nutrient-rich soils, is winter-hardy. Possible exclusions: - not native - somewhat toxic - can grow very large

We have a rather old wisteria. It’s hell. It seems to root within a 5m radius, where hardly anything else grows well that can’t cope with the root pressure. It grows practically overnight and tries to form its own jungle.
