I asked about growing wisteria in this group a while back, and after
doing some research I settled on the above cultivar. It's non-invasive,
doesn't put out suckers, and has beautiful light-blue flowers. It grows
to 10-15 feet, unlike the Oriental varieties which can go more than 100.
It'll be growing on a swing frame made of 6x6 lumber, so its strength
shouldn't be a problem. I also planted it in a large pot with the bottom
cut out, just in case. Got it at Home Depot for 19.99.
