Hi, I have never eaten any chile peppers hotter than Japaleno Peppers, which I grow in my garden each year and use generously in cooking. I usually buy the small plants in the spring, that are sold in different green house places. By subscribing to, and reading the Chile-Heads-Digest, I have been inspired to grow some hotter peppers next spring in my garden in southern Missouri, near Truman Lake. What would be a good choice for a "next step up in degree of heat" from the Japaleno Pepper? Also, what is the very hottest pepper that would likely grow in Missouri climate conditions? What are the best sources for ordering "quality" seeds to plant in my garden next spring? I will appreciate any suggestions anyone can give me. Marguerite Ruch
