The \u2018Serrano’ Hot Pepper Plant produces one of the hottest and easiest peppers to grow. They do not beat out Habaneros but they are 5 times hotter than the Jalapeno, they reach up to 2 inches in length. Serrano Peppers work well in salsas and sauces because they do not need to be peeled or seeded before adding. Simply roast, remove the stem, and add to your favorite spicy recipe.
