Wisteria for zone 4?

I would love to grow wisteria but I live in Central New York state, at a fairly high elevation. Are there any wisterias that would bloom here? Is there any hardiness difference between the tree and vine form?

If there are no hardy varieties, can they be grown in pots and brought indoors n the winter?

Thanks, everyone, in advance.

I believe that Wisteria macrostachya is the hardiest species and it would be hardy in zone 4. It's not as common as the Asian wisterias though so you may need to look around for it. Forest Farm offers a few cultivars of it, but you may be able to find a source closer to home too. http://www.forestfarm.com/products.php?params=plantName:wisteria%20macrostachya As far as tree form vs vine form--the tree form ones are that way because someone pruned/trained them that way, if allowed to grow naturally they will be vines. So tree vs vine form won't affect the hardiness.

Wisterias can be grown as mentioned either as a tree or vine depending on how much space you have to facilitate a HUGE vine or a tree that can be contained by good pruning, either tpye of growing requires a fair amount of work especially in early years.
The vine needs pruning 2 times a year but this begins after you have let the vine reach and covered the area you wish it to cover. Most Westerias are very easy to get out of hand if pruning is neglected, but also the vine requires a really good strong climbing frame that again, depending on area you wish to cover, has to have a structure that will take the weight of such a plant.
I am not trying to put you off as there is in my oppinion nothing more beautiful than a spring flowering Wisteria that has long tapered hanging bunches of flowers.

To grow a tree form, you again require a good strong single pole / support as this plant will romp away and the main trunk will be thick and have to support a heavy top growth of many branches till you can learn to prune the branches properly.
I know there are some books in our Libraries and have seen several in your USA book stores on the subject of pruning plants and Wisteria was mentioned.
They like a rich soil to start with, full sun and prefere a South or West facing position,
Hope this helps you understand what will be required when your selecting your pant, there are some new types on the market now and all are lovely no mater what type you choose, some are easier than others re training and tieing the long whip like tendrils, but are one of my favourite Plants.

Make sure the plant you choose is of flowering maturity as there are some growers will sell you a good sized cutting but it could take another 10-15 years before you get a flower on it.
Good Luck. WeeNel.

What you're saying is true for the Asian wisterias (W. floribunda and W. sinensis) which are the most common types that are grown, but those will be more questionable for hardiness in zone 4. W. macrostachya isn't as vigorous of a vine and I don't believe it has the issues with taking forever to bloom (but it's also worth noting even with the Asian wisterias, it's typically just plants grown from seed that take 10-15 yrs to bloom, ones grown from cuttings typically take less time)
