Are you referring to the big blue sculpture thing of mixed semps and aeoniums etc.?
I do have it inside now( DD thinks too early) I also read I will need to harden off these plants in spring when they go back outside.
I am pulling back from Echiverias and kalanchoe.too much trouble.
You are right,the semps will be fine in winter here. Guess I will move the plastic and tall pail to the garage.We get temps below 30 and as low as zero.
