Fun Facts
- 🌱 Illumination Orange peppers change color from green to orange as they mature, with the color change triggered by shifts in chlorophyll and the production of carotenoid pigments—the same compounds that make carrots orange.
- 🌱 This ornamental pepper variety is technically a fruit (botanically speaking), not a vegetable, as it develops from the flower's ovary and contains seeds.
- 🌱 In warm zones, pepper plants can live as perennials and produce fruit for multiple years, though productivity typically declines after the first year.
