Hi Zappa, I've heard that one to. I also have heard that depriving a wisteria (instead of having wet feet) from water in the summer in short bursts, say just a light sprinkle for a week at a time repeated every 3rd week for two months will induce flower buds. I'm not sure about any of these except the ones I use. A pine mix for a potting medium and messing with their toes as often as possible.
Well aside from the fact that its totally out of its environment, the lack of humidity, I think your missing one important point about wisteria they send out tendrils that grow at amazing speed and get very, very long. So unless she wants her office to look like a bio-dome gone a rye, I would shy away from it.
My potting mix for wisteria is basically a pine mix with a good amount of peat added, they like acidic soil. Bloom is in spring exactly when depends on your area. You will get a second and even a third bloom of smaller racemes later in the year as well, which always puts a smile on my face when all the flowering stuff is gone. A deep pot is always best for two reasons. The first is cool moist roots and second is their roots grow fast and will fill a pot rather quickly, which in itself isn't a bad thing since some believe that a root bound wisteria is more apt to bloom consistently.
Koyote, I do understand, and thought I had given you sound advise in the previous thread. I have never attempted to take a plant that needs the outdoors and stick it in my home or office, for more than a day or two. The exception being an event were said tree is on display. I have not even put tropicals inside my home. The closest they have ever come to inside living is my green house when the temps get into the fifties. Inside a home the environment is suited for human habitat, not plant. It is one thing to try and bend a plant to your will visually. It is a whole different story to will a plant to live in conditions that it can't over a prolonged period of time. However, if you feel you must try...you must try.
