I grew two types of red peppers this year: one hot; one not. I'll talk about the one that's not first. It's called Bell Pepper "Red Beauty." I bought it as a very small plant rather than growing it from seed. I planted it in mid-May and it started producing about a month ago. But you should know that first the peppers are green and then they turn red. It's perfectly fine to eat them when they're green, but I think they get sweeter once they turn red so I wait. And these peppers are very sweet (they have 0 Scoville units, remember Scoville units?) Red Beauty is an annual that requires full sun, grows to about 24" high, and the pepper is about 4-6 inches from top to bottom.
Serrano hot pepper
The second red pepper I grew is the Serrano. And it's hot. Like Red Beauty, it starts out green and you can use it then if you want. I mostly use serrano when I make salsa. Full sun for these as well.
Neither of these peppers has been bothered by pests this year and they demand nothing in the way of maintenance. Also, I like to plant them with other things in one container. For example, I have my serrano planted in a container with basil. Neither has seemed bothered by being paired together.
