Fun Facts
- 🌱 Sunfire peppers display all three color stages simultaneously on the same plant when mature, creating a natural 'traffic light' effect that makes them particularly popular for holiday decoration
- 🌱 Although called peppers, these are not related to black pepper (Piper nigrum); they belong to the Capsicum genus and their heat comes from capsaicinoids rather than piperine
- 🌱 Ornamental peppers like Sunfire are often bred for maximum fruit production rather than size, resulting in plants that may produce 50+ peppers in a single season on a compact form
