Calla lily care in winter

[Nenanena]

I have a gorgeous calla lily in a pot that we’ve had as an indoor houseplant since earlier this year. Looked online to see how to care for it indoors over the winter and I’m flummoxed as to where I can put it. I’m in the south-east and we don’t have a conservatory or greenhouse. See attached image.

Any success stories using a different approach or ideas about how I can provide what it needs?

I’m in the south east. I leave mine in the garden with a bit of fleece on when it’s frozen. Touch wood they come back each year

So you let it get rained on? I was reading something about them needing a period of dormancy but this may have been the outdoor ones? I think with those you put them in a dark place…
