I am so jealous of your Coelia bella, Ursula. If mine was ever a "star", it is now a fallen star.
I have been back and forth about putting mine outside and subjecting her to lows in the mid to low 40's and highs only in the 60's-low 70's. She is now cozy in a greenhouse but shows no sign of happiness.
The greenhouses get no colder than around 60 F.
