I have had a Wisteria vine in my back yard for the last 7 or 8 years and it is blooming now. It has bloomed year we had it as it is female and the bees love it. In the deep south they really get huge because they can go all year around but in northern Indiana mine goes dormant every year.
I trim the seed pods off because thats using energy needlessly for the plant and i have no plans to add another. My Wisteria has a death grip on the metal trellis it has wrapped itself around over the years and the trunk has grown from 1 inch to 5 inches around.
I have taken no extra overwinter care except to keep the ground around the trunk mulched. I will add a pic very shortly.
