I have a thread in the Trees forum as I am looking for an Ornamental Tree for my yard. The tree I had wanted to get appears to no longer available, and I am not sure if I should wait till next year, so am considering my options. Thread is here: http://forums2.gardenweb.com/forums/load/trees/msg0421215632224.html?4530
One that I am considering is a Wisteria Tree. Since it's really a Wisteria vine grafted onto a trunk & root system, I thought it might be most appropriate to post in this forum.
Does anyone have experience with Wisteria Trees? I have read they don't grow any taller than when they were grafted, but the trunk will get thicker and stronger. Is this true? If so, how tall do they come? I am wondering if this will be an appropriate substitute for the Crabapple I had planned on, but if it's not very tall, perhaps not. I see photos of what look to be very old and tall wisteria trees, online. I wonder at that if they don't grow taller.
I'm also wondering about the root system on the tree they were grafted to - how deep or shallow and how wide they get. Does anyone know what the most common type of tree is that's used for the grafts?
Thanks for any help offered!
