Wisteria in Iowa: good? bad? hardy?

janetgia(5b IA)July 1, 2009

I'm just curious if anyone here is near zone 5b/Iowa and grows Wisteria, and whether you've had problems with it being aggressive/invasive, or whether it's well-behaved, or not even hardy, or anything else in particular. Have heard it can be aggressive, and I do NOT want to get into another plant war such as the one I LOST against trumpet vine at our old place. :)

Yes you can grow it. (see link below)
BUT:
Wisteria is extremely invasive. You MUST prune!

My wisteria has eaten my greenhouse.

Libby, do you have trouble (in addition to the pruning requirements) with having new plants springing up everywhere? I visited the nursery today and saw that they carry Chinese wisteria - it looked strangely like trumpet vine, the root system of which was the problem at my previous house.

I haven't seen any new plants popping up from the root system, but I've read these can be invasive. I've also heard wisteria can be very hard to get rid of.

In zone 10, dry warm Mediterranean climate, wisteria is IMPOSSIBLE to erradicate. Ask me how I know... Plant it REALLY FAR from anything that matters and be prepared for a life long battle to keep it in bounds. At least here, that's how it goes. Beautiful vine, but I would never plant another unless I had the acreage for it not to tear anything down. That means more land than I will ever be able to afford.

BTW, here new plants do pop from the root system. Even a tiny bit of root will originate new plants. The plant laughs at Roundup, even at those early stages. I don't know about Iowa, though, as your climate is so different.

You have been warned :-)

When I moved in, there was wisteria growing through the trees by the road. I cut it down, a 2" thick rope of branches coming out of the ground. That was a bad idea. It's now popping up all through the perennial bed. I pull new growth and it just keeps coming back. Even after two weeks of no rain, there's new growth on the wisteria. Perhaps in your zone it won't be quite so bad, but I'd listen to Eduarda...far far away from anything that matters.
