I know, but . . .they come in flower because they've been kept container grown and are under the misconception that they've reached maturity, in the pot. Therefore they flower, which suits the grower and supplier because they sell quickly. However, once they get out into the big wide world and discover soil, space and freedom to grow, that's what they do, at the expense of flower. It can often take a few years for a wisteria to reach 'maturity' in the ground and start producing flowering spurs. I think that's what yours has done, enjoyed itself and grown. If it's healthy, enjoy its youthful vigour and hopefully it'll flower next year or perhaps the year after.
