I live in Tucson, where Mexican food is king. I admit that I haven't pushed myself to try the hottest of the hot, but I love the flavors and traditions of hot peppers. I have a mystery pepper plant that I received in a plant swap. Nothing I've found on the Internet looks like this pepper. I don't even know whether it will stay green or change color as it ripens. Hoping somebody here can I.D. so I can pick it and taste it at the right moment. Thanks!
