I'm going to be Debbie downer here. I'm sorry. 249. 249 individual plants were killed overnight by freezing Temps. Now mine dropped to about 20 to 25 F, so colder than yours. It wasn't even supposed to be that cold.
I feel your pain. In January 2018, we had a nasty cold snap roll in: 200 contiguous hours well below freezing (that's nothing for up north, but it was brutally cold for my location). I had moved all of my small pots into the garage, but I left 4-5 large pots (12+ inches / 30+ centimeters in diameter) outside. I lost a beautiful Sarracenia flava var. ornata that I got from Mike Wang 4 years earlier:
The pot froze solid. In the spring, I prayed for the sight of a green sprout but saw no sign of life. When I unpotted it and checked the rhizome, it was brown all the way to the core.
Never again. I made a portable cold frame from PVC pipes and connectors, plastic sheeting, and a small greenhouse heater. On those infrequent occasions of exceptionally cold weather, I put up the cold frame, set the heater on 40° F (4° C), and my plants are safe (as long as we don't lose power).
