Wisterias fill the air with a heavenly scent that I look forward to each blooming time. There are different varieties that determine when the bloom will occur.
Japanese Wisteria (wisteria floribunda) I'm afraid I don't know when they bloom, but I think it's only once.
Chinese Wisteria (wisteria sinensis) blooms late spring to early summer.
American Wisteria (wisteria frutescens) blooms early to mid spring and again in the summer. I have heard the rebloom can be sporadic but I have a wonderful specimen and it blooms again without fail. I always recommend native planting for numerous reasons not least of which is protect biodiversity which is in danger. Birds love it for nesting and protection from the elements.
Kentucky Wisteria (wisteria macrostachya) blooms 1st in June and like the other native blooms again in summer.

To be very honest, you should not plant any perennial with wisteria. It will kill anything it is planted with eventually. I would instead say that you might want to think about an annual, like morning glory or cypress vine, that wisteria would not be able to strangle and would reseed every year. As for winter interest, wisteria vines have a very sculptural shape that many people appreciate. You can add twinkle lights as well, to highlight those shapes and make them pop a little more in the landscape.

Wisterias normally do not transplant well. You can try it, but you will need to cut the plant back pretty severely in order to ensure that it survives being transplanted.

It might damage the plant to cut it away from the stake. If it is able to be untangled from it without hurting it, you can do that, but likely your best option will be to set the stake against your post. The wisteria will eventually grow away from the stake and up the post. Wisteria are notorious for not growing the first year and then going wild the second or third year.
