Answer

Unfortunately, wisterias can be very temperamental. Some wisterias never bloom at all.  Hopefully, that is not the case with your plant. However, most wisterias do not bloom until they are about 5-7 years old, so yours still has a chance.

There are a number of things to look out for and try:

1. Is your plant located in full sun? Wisterias need at least 6 hours of sun a day to flower well.

2. Is your wisteria getting too much nitrogen? Since you say that your plant is very green this may be case. If you are fertilizing it make sure that you are not using a fertilizer high in nitrogen. Try applying a superphosphate fertilizer.

3. Prune the wisteria every year. Start in late winter or early spring by cutting back to within 3-4 buds from the base. Then, in summer, cut back any tendrils longer that 6 feet to about 1 foot.

4.Root pruning may help. Use a shovel to cut the roots in a circle at least 3 feet from the plant.

More: To maintain trained forms and enhance flowering, wisterias must be rigorously spur-pruned in two stages, in summer and winter. Even wisterias that are allowed to ramble informally flower markedly better when spur-pruned. 

Once the basic framework of the wisteria plant is established, the aim of pruning is to control extension growth and to encourage the production of lateral flowering spurs. the current season's shoots are cut back in two stages (see above). Wisterias are long-lived and, if pruned annually, seldom need renovation, but can be done if needed over time in stages.Wisterias can be trained as standards, on a wired wall, pergolas, arches, fences, The flowers come in white, blue-violet or deep purple, pink, or apricot.
