The Sweet Banana Pepper (Capsicum annuum) is a mild, sweet pepper variety, known for its vibrant color and versatile culinary uses. This All-America Selections-winning heirloom is perfect for snacking, salads, and pickling, with a mild heat level around 500 Scoville Units. Sweet Banana Peppers are best when they reach 6-7 inches and have turned a light-yellow color, although they can ripen to red.
