What a nice plant! I had to look it up, not being real familiar with a lot of tropicals (up here in zone 6). The basic thing about this plant is that it is only hardy to zone 9. You are lucky it survived in your garage. I did find this:
In Zone 8 the shrub dies to ground after hard freezes but resprouts in spring. It typically recovers quickly enough to bloom, but probably not set berries, by the following season's first frost.
It looks like you are probably in Zone 7, even worse from the plant's point of view. So it may yet bloom, just a lot later than it would have, if not so cold stressed. If it does, then this winter you may want to bring it indoors, instead of leaving it in the garage. I have an angel trumpet I bring in every fall. I have a lamp on it for extra light. Being designed to grow a lot closer to the equator, where they never have such short days as we do in winter, it needs the extra light.
