The seeds can be rooted, but I'd recommend buying a named variety.

I have a vine too and have a similar love/hate relationship. They are
very fast growers and never in the direction I want them to grow in.

My wisteria grows across an open trellis above my patio. The blooms
hang down and create a gorgeous, dramatic purple canopy over the patio.


BUT they develop huge seed pods. The pods drip while they are forming
seeds. At least the drips aren't sticky. When the seeds are ready the
pods explode - sending the seeds and pod out like shrapnel! If you've
had heavy blooms in spring you'll be ducking like crazy come fall.

I also have to spend a lot of time keeping the rootstock from sending
out more branches. They need constant trimming at the base - and at
the top to keep it in line. If I were to plant another one I'd pick a
spot where they can be admired from afar!
