This is a Chinese Wisteria which is pretty finicky in Chicago's climate. I purchased this standard ( vine grafted onto a tree trunk ) 7 years ago when it was reduced from $500 to $100. I was about to whack it down when I decided to go all out in a last ditch effort to make it produce blooms. I root pruned it severly and cut back the branches to within a few shoots and applied triple phosphate . Of course I think I also threatened it with " Bloom dammit ! " My efforts finally paid off.
Now if we can have some sunshine please and get the celebration started.
