Oh my, Sharon, I did not know that you had woven them into trees! So fantastic! I think I may have told you earlier that I have a wisteria here that I bought the first year we lived here full time, so 3 years ago. I planted it in a pot with the idea of overwintering indoors, but that has never happened, and by now I rather suspect that it's roots have made their way through the drainage hole and into the (very rocky) ground below, at least I hope so. It was blooming when I bought it (I have read to only buy one that is in bloom, as otherwise it might be a "non-bloomer"). I didn't get any blooms last year, but I hope it blooms this year. Do you prune yours at all?
Also another quick and funny wisteria story... when Tony and I lived in Arizona, in his house there, I was longing for a wisteria. Then one day I walked out the back door and noticed that this viney thing that I had walked by a gazillion times before had a purple bloom on it... a closer look led me to discover that I HAD a wisteria. A little TLC and it was very happy and bloomful!
