A neat trick that I picked up is to intertwine Wisteria macrostachya
in amongst your Wisteria floribunda plants. W. macrostachya blooms
about two weeks later than W. floribunda, so you can extend the effective
bloom time of your Wisteria arbor/whatever pretty easily.
Besides, W. macrostachya is a cute native that's more cold hardy. :)
