The most popular pepper here is the hawaiian pepper which is the same as tabasco pepper. It is medium hot and used for everything from soup, stews, salsa, pickles, fenadene, and chile pepper water. It also can live a very long time in the ground. I have one that is over 10 years old.
Serrano, similar to Jalapeno, but Jalapeno's lately have not been consistent, some were hot some not on the same plant. Serrano have been more reliable
Anaheim peppers good for stuffing and chile rellenos, and not a bad frying pepper. It has only a little heat 500 scovilles so it isn't very spicy.
Sweet banana pepper. It is a good frying pepper, more productive and less trouble to grow than bell peppers
Chinese Giant Bell Pepper a large heirloom pepper. The only thing is here none of the bell peppers last very long so the most I wll get are about 5 peppers. Other places people say that peppers last until frost.
California Wonder, Yolo Wonder and Yellow bells have also done fairly well athough they are smaller than Chinese Giants.
Cayenne. This is about as hot as I like it. The pepper pods can be dried. Dried pepper flakes are even hotter but while the pepper is hot is still has a nice flavor
Happy gardening in Hawaii. Gardens are where people grow.
