I'd say mikeod's method should work pretty well. If you cover, use lights under the cover (Xmas lights work well), you can pretty much save most plants in Florida's freezes. Without cover and/or putting under a roof, they don't do well. Sometimes you get lucky and they will come back, but I found that last year even drastic cutting didn't help many of the BVs -- they just couldn't take two weeks of freezing. It also helps to be sure your sprinklers are off during freezes -- notbing like frozen water on tropical plants to totally shock them.
