Timothy,
Many times I have put rooted cuttings with NO leaves or shoots into potting soil in cups and suddenly from deep in the cup a shoot will work it's way up the side and leaf out on top, an inch from the main cutting. If there are roots, there will be leaves!! Not to worry!
In ground, people have pruned their trees back to almost nothing, and when the weather warms, new shoots appear from odd places.
I'd say "Good luck," but you don't need it! You have roots! Leaves will surely follow!
