Depending on the variety, some take a few years to reach a maturity level to bloom. Another reason may be too much nitrogen which will produce a lot of leaves but no blooms.
Wisteria can be tardy bloomers, which is why people often buy them in bloom. But at least your wait is over.
They seem to start blooming when the limbs begin growing horizontally. The initial vertical growth isn't conducive to making bloom buds.
First year was just growth, I cut them down expecting the following year that they harden up, more growth. So I replanted it next to our house and left the growth to wind around the sturdy trellis, leaves and not much else, this year however I see flower buds and successful growth which makes me smile. I also fed it plenty of Miracle Gro early. Our visiting "hummers" (main reason I bought the plant) will be around more often. Thank you all for your comments, I appreciate it.
