hahahaha...I have a Blue Moon Wisteria.....I can tell you for a fact that it can languish for 5-6 years in a 5 gal pot...I checked it yesterday, still alive...I will pot it larger, give it fresh soil, try to keep it going until I see if I will ever find a spot for it...my main problem is the color of this house and not wanting to repaint it yet...until it's breathing its last breaths...it got a new roof, but...so, yesterday I'm looking at our garage door...jer wants to build an open roof of sorts onto the opening so he has more room to work on things, it's his shop....but I was studying it and wondering if I could put that Wisteria across there...you convinced me, I don't think I will....this house is basic, a box, no character and I was thinking we might build an arbor across the front, but think I want green across there, think the Wisteria would be too much...and I love Wisteria......if it were white...lol..I saw a white one the other day, running up through the trees, gone wild...I need to go take a pic...
