Wisteria

They can take several years to flower, I'm afraid. You will have to be patient! Which species you bought also has a bearing on how many years, as some flower sooner than others.

Spritz quite right to say they can take years - some never flower as from poor stock others pruned incorrectly and potential flowers removed.If you happy with the pruning side of things I would suggest buying another next spring when you can see flower buds forming and plant alongside.Many buy wisteria after flower season thinking it will have a good few months to establish itself.Given the size of wisteria in garden centres [ and the price ] they should all be capable of flowering - so if you cant see flower buds dont buy them and ignore the - it could take years principle.
