I'm sure some people already know this, but you can overwinter pepper plants and keep them growing for years. If you love hot peppers and live somewhere north of zone 9, I highly recommend it. I didn't know you could do this until a couple of years ago when I grew a ghost chile from seed. Ghost chiles take forever to ripen fruit. I think 140 days from transplant is typical. That first year, I had a bunch of green peppers by the end of October, but the nights were getting too cold to keep the plant outside. I started bringing it in at night with some fig trees that were still ripening figs. After a couple of weeks, I just kept it inside full-time. The fruits ripened in December and the plant still looked good, so I decided to keep it. The next year, the plant produced a ton of fruit, and much earlier, too.
Overwintering peppers is similar to overwintering citrus. You just bring the plants in when the weather outside becomes too cold for the plants to bear. Put them by a window with sun, and they'll do fine. Supplemental lighting is helpful, but not essential. Peppers don't require as much light as citrus, and in my experience, pests haven't been an issue. My hot pepper season now runs from June or July to December or January.
