Cayenne Pepper
Hot Pepper
Cayenne pepper is a legendary hot pepper that brings serious heat and deep flavor to gardens and kitchens across USDA zones 9-11. This member of the nightshade family grows as a compact to medium-sized plant reaching 12 to 48 inches tall, producing abundant showy red fruits that are far more ornamental than their fiery reputation suggests. Despite the low confidence score in our data, cayenne remains one of the world's most recognized and cultivated peppers, prized for both fresh and dried applications.

Highlights
Cayenne peppers are remarkably adaptable, they thrive in full sun with moderate water and even tolerate drought once established, making them ideal for gardeners who want impressive yields without constant fussing. The plants themselves are nearly as ornamental as they are productive, with abundant upright fruits that catch the eye while delivering the intense heat cayenne is famous for. These peppers demand warmth and patience during their early growth, but once established they reward you with prolific harvests season after season.
Common Uses
Cayenne peppers excel both fresh and dried. Fresh peppers are sliced into salsas, stir-fries, and hot sauces where their intense heat and complex flavor shine. Many gardeners allow fruits to fully ripen on the plant, then dry them for grinding into powder, the classic cayenne spice that brings heat and depth to countless dishes. The peppers can also be fermented, pickled, or used fresh in marinades and rubs for meats.

Care Instructions
Start Indoors
Sow seeds indoors 6 to 8 weeks before your intended transplant date, placing 3 seeds per peat pot in a warm, sunny location and thinning to 1 plant per pot once seedlings emerge. Keep soil consistently moist and maintain warm temperatures to encourage germination.
Transplant Outdoors
Transplant into the garden after all danger of frost has passed and nighttime temperatures are consistently at or above 55°F. Harden off seedlings gradually before moving them to their final location. Space plants 18 to 24 inches apart in rows 18 to 24 inches apart, being careful not to disturb roots during the transplanting process.
Harvesting
Allow peppers to fully mature and develop their deep red color on the plant for maximum heat and flavor intensity. Harvest by cutting (not pulling) peppers from the stem. Fresh peppers can be picked at any stage of ripeness, but for drying and grinding into cayenne powder, allow them to fully mature to deep red. Mature plants will continue producing throughout the warm season with regular harvesting.

History & Origin
“Peppers were among the earliest plants domesticated in the New World, with archaeological evidence pointing to their cultivation in ancient Mesoamerican societies. The cayenne variety takes its name from the city of Cayenne in French Guiana, though its ancestry traces back to Central and South American origins where indigenous peoples had already developed sophisticated pepper cultivation practices over centuries. European explorers encountered these peppers and carried them back across the Atlantic in the 16th century, where they gradually spread throughout Africa, Asia, and the Mediterranean, eventually becoming foundational to cuisines worldwide.”
