with the previous posters...
Are you trying to grow wisteria indoors? I can't imagine that it's happy in the living room.
If that is the chinese wisteria... you should treat it like the weed that it is... plant it in the yard, and then plan to keep cutting it back.
It may look like a delicate hot house plant right now, but that's a trick...
