from me too Jim; that is one beautiful
Queen-of-Sheba Vine (Podranea brycei) 
I can only imagine how amazing it looks when full of flowers!
I agree with Chelle, the all purpose plant food is probably providing high nitrogen which will help with lush growth but doesn't much help with producing blooms. I'd try a low dose of bloom booster fertilizer (one with a high middle number) to give it a push to produce those lovely flowers. I have the
Pink Trumpet Vine (Podranea ricasoliana) growing in a container and will begin feeding it with bloom booster in the next week or so.
