There are a lot of variety in the pepper family and what you decide to grow may depend on your region. Some seed companies provide a map of all the regions and you will need to find yours in order to choose the best variety for you. Do you want peppers that are sweet? Like bells and bananas? or hot like jalapenos or habaneros? What ever you choose you may want to stick with the smaller varieties. It is generally recommended that the smaller fruits (hot or sweet) are easier to grow. If your summers are unusually cool or extremely hot (or if you’ve just had trouble growing good peppers in the past), the smaller kind may be for you.
