The houses I stage my standby plants that survive the cool homes are....
Rubber tree
Jade plants
Peace Lilies
Schefflera
Spider plant I use in the kitchens and bathrooms where I want a hanging plant.
These plants are in big pots on the floor near windows.
Two years ago the furnace failed and the pipes froze and busted. The entire house had to be gutted and walls and floor replaced. I did not lose one plant. No water got in the pots just the floor and my staging furniture that was in the house.
The difference of plants living in a cool home and outside in the cold is different. There is no wind and if they are not moist for long periods they do not freeze. Pipes freeze because of the water. The same thing will happen to the plants if they have too much water in the soil. If you keep them on the dry side they do great. The rubber tree I water in Dec and do not water it again until March.
I have been doing this for 10 yrs. I know it can be done.
