Neal: Wow, I guess winter is truly upon some parts of the country already ... it just seems so early to hear of upper 20's but I saw a news report yesterday that showed Minnesota with a lot of snow and it stated some parts of the country can expect temp's 40º below normal for the time of year ... I hope that was a misprint!
Your Cape Honeysuckle should be fine, just be sure not to over-water during the winter months; keep the soil a tad moist but not consistently wet. Even if it loses a lot of leaves (or all of them) it should re-sprout new foliage next spring when you can safely move it back outside again. I've had some tropicals go totally leafless and I thought they were dead but a gentle bend of a stem or branch showed no brittleness at all and new leaves appeared once I was able to move them back out to the deck when warm weather returned.
.... currently 74º here in sunny Florida.
