After a couple of hours searching the web, I'm just going to post my question and hope someone with experience can answer.
A friend of mine wants to get rid of some in-ground wisterias, Wisteria sinensis I believe. They're decent size, my wife loves wisteria flowers, and all it would cost me is the gas to get to his place and the time and effort to dig one.
But I've been unable to find definitive information on the amount of cold a wisteria can tolerate. Harry Harrington advises not letting them get colder than -5 C (about 23 F) because of the water content of the roots. Plant-hardiness sites list wisterias as hardy to USDA zone 5. And maybe I haven't yet looked far enough, but that's all I've been able to find. <frustrated>
In a "normal" winter here, we're supposed to allow for lows down to -20 F (about -29 C.) We've haven't seen that every winter, of course, but that's what must be allowed for.
Any feedback is welcome, particularly from anyone with wisteria experience in a similar climate. Thanks!
