You have the jade vines?! *drool*
I'm in 9b and we didn't get a freeze this year either but my Pudica were all nipped by 38 and I had to cut all the tips. It did freeze last year and I saw every big plumeria in town freeze to the ground, but all started growing again from the roots. The small ones perished for good. Firestorm from JJ's is the most cold tolerant variety I've found - it started pushing inflos a month ago and I left it plunged outside with no protection. Yours sound too big for this, but I've started planting in the ground under my greenhouses, that way I can slip the cover over them and hook up a heat lamp.
