I mostly only buy cold hardy bromeliads since we can have many hours and days dip in the 20's here in Central FL. I've never lost one, but have had damage to some of the leaves a few years back when we had some very cold winters. Most of mine are in the ground under oaks, some are hanging in baskets.
I've only had the one Cryptanthus overwinter and they were mild winters, my other three were just acquired since spring, so I'm not sure how cold hardy they are. I know I've left my Pink Starlight out last winter to 35 one night for a few hours and didn't faze it, but I did put it inside the next few cold nights to be safe.
My hoyas, and orchids go in my FL room, I've pushed some and lost some over the years, lessons learned the hard way.
