Chiltepin Chili Pepper Seeds are open pollinated seeds. We rank this one among the top 10 hottest peppers on the market, although some rate it even higher on the heat scale. Don't be fooled by the unassuming size of these pea-like, 1/2 inch fruits - they pack a wallop! Prolific, 8 to 10 inch bushes produce extremely hot fruits whose small size is very versatile in recipes.
