Cayenne Long Red Thin Pepper is a pre-Columbian heirloom that brings authentic heat and heritage to any garden. This upright annual grows 18-24 inches tall and produces the slender, bright red peppers that define the cayenne standard, reaching harvest in just 70-79 days from transplant. Hardy in zones 4-13 and naturally deer resistant, it thrives in full sun and tolerates both heat and drought with remarkable resilience, making it one of the most reliable hot peppers for gardeners across diverse climates.

Named after the Cayenne River and traced back to Pre-Columbian origins, this variety represents genuine pepper history. The long, thin red fruits pack serious fire, ranging from 30,000 to 50,000 Scoville Heat Units, and mature quickly enough to reward impatient gardeners. Its drought tolerance and heat resilience mean it performs brilliantly in containers, raised beds, and garden plots with minimal fussing, thriving where other peppers struggle.
Cayenne peppers excel at drying, the traditional preservation method that concentrates their heat and deepens their flavor. Fresh peppers work beautifully in hot sauces, infused vinegars, and spicy condiments. Ground cayenne powder from dried fruits has long been a staple in spice cabinets, bringing controlled, measured heat to dishes from scrambled eggs to roasted vegetables. Their long, thin shape makes them particularly suited to hanging and air-drying, a practical advantage for home preservationists.

Start seeds indoors 6-8 weeks before your last spring frost date. Pepper seeds germinate best at 75-85°F with consistent moisture. Plant seeds 1/4 inch deep in seed-starting mix and keep warm and humid until sprouts emerge, typically within 7-14 days.
Harden off seedlings over 7-10 days by gradually exposing them to outdoor conditions. Transplant outdoors after the last frost date once soil temperature reaches at least 70°F. Plant at the same depth they were growing in containers, spacing 18 inches apart with 36 inches between rows.
Peppers reach edible maturity at 70-79 days from transplant and can be harvested at any stage, though they develop maximum heat and flavor once fully red. Peppers will turn from green to bright red on the plant; you can pick them red for immediate use or harvest just-mature green peppers if needed. Cut or carefully twist peppers from the stem rather than pulling, which can damage branches. For drying, allow peppers to fully mature to red on the plant, then harvest by cutting the stem cleanly. Wear gloves when handling to avoid capsaicin irritation, especially if you plan to touch your face.
Minimal pruning is required given the upright growth habit. Remove any lower leaves touching the soil to improve air circulation and reduce disease pressure, particularly as the plant matures and fruit weight increases.

“The Cayenne pepper carries one of the most storied pedigrees in the capsicum world. Pre-Columbian in origin, it was named after the Cayenne River in French Guiana, a naming that speaks to its journey from the Americas into global cultivation. This is genuine heirloom material, preserved and grown by gardeners and seed savers for centuries, representing a direct line to indigenous pepper cultivation practices. Its endurance across centuries and continents speaks to its reliability and adaptability, qualities that made it invaluable to colonial traders and remain essential to modern gardeners seeking authentic, open-pollinated genetics.”
