wisteria

I only know that with some Wisterias you have to be patient because they can take several years to start flowering. It also depends on how your plant was grown. If you bought a grafted one, they flower much quicker, so I'm told.

Yes, I think I read somewhere that it takes seven years for a wisteria to flower from being a seedling. However, my sister-in-law's still hasn't flowered after about 8, probably because it's in a pot?

I had a wisteria growing in my garden for 8 years and it never did flower. I used to get buds, which promptly dropped off. I disposed of it years ago, but I would love to replace it now. Does anyone know (1) where a mature plant could be obtained as I do not want to wait seven years to see a flower and (2) would it be suitable to climb a wisteria up trellis. I know that the stems can become very thick and ugly and wonder whether this would "topple" the trellis over.
