Fun Facts
- 🌱 Mahogany Jewel peppers change color multiple times as they mature—starting green, progressing through yellow and orange, and finally achieving their signature deep mahogany-red hue, all while remaining on the plant.
- 🌱 Ornamental pepper varieties like Mahogany Jewel are technically edible fruits, though they were traditionally bred more for appearance than flavor, making them equally at home in a decorative container or a kitchen garden.
- 🌱 The intense color of mature mahogany peppers is due to carotenoid pigments, the same compounds that give carrots and sweet potatoes their orange hue.
