I think most people don't know this, but most pepper plants can be grown as perennials in tropical/subtropical climates (they can live for several years). If you grow them in pots, bring the pots in early (well before the first freeze). It might shut down a little if it gets too cold and dark (mine usually do) but then rebound and grow bigger the next year. Thought I would throw that out there. I have a 1.5 year old habanero and it produced very well this year and is still alive. I am hoping next year will be even better.
