The leaves will probably come after it is done blooming. Some of them put all their energy into the flower first, and then will produce leaves later. I'd say about 2/3 or more of mine do that. After blooming, I give mine a rest of about 3 weeks, just water them, and then start fertilizing them regularly after that. Until about August, then I stop the fertilizer and reduce the watering so they can get ready to go dormant for the winter.
