Answer: I have to admit I read your question twice, that does seem small and especially to be bearing peppers. But, there are some ornamental pepper varieties available that mature to be very small plants, some as small as 6 inches (Medusa for example) so what you are seeing may be normal. Since they are fruiting the plants must be fairly healthy. The only explanation I can think of beyond the specific variety you are growing would be possibly an application of growth regulator prior to purchase at some point. This can sometimes affect height later on in the season beyond its intended time frame. You might also want to consult with your local county extension and see if they have any suggestions. In the meantime, be sure to take a photo!
