Mustard Naga-(Capsicum chinense)-The Mustard Naga is a mustard colored variant that has appeared multiple times in our growing of the Black Naga. Finally, we saw consistency in the pod shapes and size and decided to grow. At first, we were not going to but a few friends in the chile community loved this version so here we are! The Mustard Naga is one of the hottest Mustard type pods around. The flavor is kind of citrus smoky, but some may say slightly sweet. Depends on your tastebuds. The Mustard Naga chile plants grow 3 to 4 feet tall.
