Nomenclature[edit]
A mature fruit will be about 2-3 inches (5–8 cm) in length and have a curved shape and yellowish color similar to a banana, giving rise to the fruit's common name. Peperoncini are often erroneously referred to as banana peppers and immature Hungarian wax peppers are frequently mistaken for them. It's not uncommon for Hungarian wax peppers to be sold in bunches of banana peppers providing more heat and less sweetness than would be expected.
