Harvest Tips
Peppers can be harvested at green stage (3-4 weeks after flowering) for milder flavor, but mature red peppers (7-8 weeks after flowering) have maximum heat and sweetness.

Fun Facts
- 🌱 The 'Firecracker' name refers to both the plant's explosive growth habit and the vibrant red peppers that appear suddenly in abundance, resembling tiny firecrackers bursting on the bush.
- 🌱 Capsaicin, the compound giving cayenne its heat, binds to pain receptors in the mouth but actually triggers a cooling sensation in the stomach, which is why spicy peppers are popular in hot climates for natural perspiration and cooling.
- 🌱 Cayenne peppers were named after the city of Cayenne in French Guiana and are native to South America, having been cultivated and used medicinally by indigenous cultures for thousands of years before reaching Europe through Spanish and Portuguese traders.
