Sorry but you are not ever likely to get this to flower! The only way is for grafted plants
It will of course lose its leaves this autumn. However will never (jamais) flower at least not true to variety and may never flower in twenty years.
We also live in Haute Vienne and have wisterias bought as plants and find them very hardy.We put one supported on re-inforcement iron bar we built as a frame work to eventually give shade on the terrace and after 4 years it has developed a very thick stem which would support itself whenever the iron rusts away.
The shade is good enough to sit outside in the hot summers -if they ever return!!!!!!!!!!
Wisterias come from the mountain regions of China and Japan. Normally mature plants are hardy. Just take yours inside a barn or whatever very little water just keep it slightly damp throughout the winter.
We took some cuttings and dug out bits of root when cutting ours back for the winter.Seems to give the tree a whole new lease of life too.Back to cuttings,they seem to be going from strength to strength now and our friends are quite happy with theirs so far too.
House is in H Vienne and hard winters don't seem to affect it unduly.Mind you the tree must be fairly old, as has quite a large trunk now.
Our neighbour across the way,says that the last two years have been great for flowering since we started pruning back hard too.
Maybe cuttings would be better than seed?Not sure on that as my knowledge of gardening/trees is v limited

PS If only I could work out how to post photo with this,would show ours off!!
On searching for advice about how to take cuttings of wisteria I found this thread.
We took a cutting of a non flowering stem from the joint so I hope that this will come to something? Have any of the previous posters had success this year with their cuttings, and did/do they flower?
Many t hanks
