I seperated a capensis last autumn and planted it in a watertight pot with a Sarra alata. This was left out over the winter under a plastic cover. It remained green although dormant and is now producing new growth whereas those indoors on the windowsill have gone all brown and look dead. I'm waiting to see if they produce new growth though but it looks like it liked it better outside. I did this as a bit of an experiment and now it looks like its paid off.
