Red hot cherry peppers (Capsicum annuum), also called cherry bombs, are spicy peppers that grow best in USDA plant hardiness zones 9 through 11. These peppers are small and round, similar to a cherry or a cherry tomato. When ripe, they’re bright red and thick, and they're often used in cooking to spice up a dish.
 
Red hot cherry peppers produce a medium heat, usually landing between 2,500–5,000 Scoville units (used to measure spiciness), but they can reach 10,000–15,000 units, which is hotter than an average jalapeño pepper. Since their taste is sweet as well as hot, they’re popular in chilies, salsas and soups.
