I have 2 Demon Red chilli plants on a bedroom window ledge, they were planted in April last year and have been giving me fruit all through the winter, there is another crop ready to pick now,I sowed them in a 3" pot then moved them to 5" pots, where they are now, we live in Yorkshire, they did take a long time to germinate so I just left them, it has paid off, I picked 15 chilli's last week.
