I mostly grow green chili peppers, I'm going to try some bell peppers from the UK next year, and some favorite sweets, and a number of super hots, besides my usual green chili's.
Last week I tried some of my Orange Tree Habenero peppers, and I really like them. Decent heat, and a refreshing taste. Some to me taste earthy, or musky, heavy heat with an earthy burn. Very hot jalapenos are like this. I love jalapeno, but not when they are too hot. This pepper had a nice clean heat, it's a keeper for me along with the fish pepper my favorite hot pepper.
For sweets I like to grow Yellow Monster and Spanish Mammoth. Sweets are not very productive here, and these have worked for me. Many good ones out there.
