I've seen wisterias grown in containers and they don't seem to mind it too much. In fact, my friend has one growing on the corner of his house twining through a first-floor balcony, but it is growing in a brick planter rather than a pot, and I don't know whether it is open-bottomed or not.

I've always regarded wisteria as being very hardy. Do they not prosper in Canada? Certainly a continental climate seems to suit them best in Europe. The best ones I've seen have been in Italy or France, where they often repeat flower in late summer on new growth.
