Fun Facts
- 🌱 Sweet Banana peppers get their name from their elongated, curved shape that resembles a banana, not from any banana flavor.
- 🌱 These peppers are less spicy than jalapeños but more prolific than many bell pepper varieties, often producing 20-30+ peppers per plant.
- 🌱 The color progression from yellow to red indicates increasing sweetness; red ones are fully ripe and have higher sugar content and vitamin C.
