I had three Worsleya plants in my greenhouse when the temperature dropped to 20 degrees F inside the greenhouse because of a propane supplier screw up. I estimate that the greenhouse temperature was below freezing for somewhere between 12 to 24 hours. The two older, larger plants were slightly damaged but survived. The younger, smallest plant died. All three plants were potted in long fiber sphagnum moss that was a somewhat dry at the time.
