Where to buy white wisteria tree

Has anyone seen the movie, AVATAR? There is that scene that shows a beautiful mystical looking tree as background, which seemed to be white wisteria. Where can I buy this tree?

I've seen Avatar. Great movie.
Wisteria does not do well in a tropical climate. A great alternative is Petrea volubilis which comes in Blue and White.

Thanks again, Dutchlady1!
