Long Red Cayenne Pepper

Capsicum annuum var. acuminatum

vegetable

Long Red Cayenne is a hot pepper variety known for its elongated, slender red fruits that mature from green. These peppers are prized for their moderate to high heat level (30,000-50,000 Scoville units) and are commonly used fresh, dried, and ground into cayenne powder. The plants are productive and relatively easy to grow, making them popular in both home and commercial gardens.

Growth Stages

1

Seedling

4-6 weeks

Tiny leaves emerge, plant develops first and second true leaves. Stems are thin and delicate.

Provide bright light 14-16 hours daily. Keep soil moist but not soggy. Maintain temperature of 70-80°F. Thin seedlings if overcrowded. Begin fertilizing with dilute liquid fertilizer at 2-3 weeks.

2

Vegetative Growth

4-6 weeks

Plant develops multiple stems, branching structure forms, leaves multiply. Plant is sturdy with dark green foliage but no flowers yet.

Harden off transplants before planting outdoors. Space 18 inches apart in garden. Water consistently. Apply balanced fertilizer every 2-3 weeks. Pinch top growth if plant becomes leggy to encourage bushiness.

3

Flowering

3-4 weeks

Small white flowers with yellow anthers appear in leaf axils. Plant is full and established with many branches bearing flower clusters.

Maintain consistent watering and soil moisture. Switch to lower-nitrogen fertilizer (phosphorus-rich) to support fruit set. Ensure adequate sun exposure. Keep temperatures between 65-80°F for optimal pollination.

4

Fruit Development

4-6 weeks

Tiny green peppers form from flowers, gradually enlarging. Fruits are long and slender, initially green and firm.

Continue consistent watering; do not allow soil to dry completely. Provide support with stakes or cages if needed due to fruit weight. Fertilize every 3 weeks with balanced or potassium-rich formula. Remove any damaged or diseased fruits.

5

Ripening to Maturity

3-4 weeks per fruit; ongoing through frost

Peppers gradually change color from green to red. Fruits reach full size (4-6 inches long) and develop characteristic cayenne shape. Skin becomes glossy and smooth.

Maintain consistent watering to prevent cracking and ensure even ripening. Continue fertilizing every 2-3 weeks. Harvest green peppers anytime, or allow to fully ripen to red on plant. Red peppers take 2-3 weeks longer to develop after turning color.

Common Pests

  • Spray with strong water jet, insecticidal soap, neem oil, or introduce ladybugs. Use reflective mulches as deterrent.

  • Increase humidity, spray with neem oil or miticide. Remove heavily infested leaves. Avoid over-fertilizing with nitrogen.

  • Yellow sticky traps, neem oil spray, insecticidal soap. Encourage natural predators like parasitic wasps.

  • Remove and destroy infested peppers. Remove plant debris. Scout for small holes in fruits. Use spinosad or pyrethrin if severe.

  • Use disease-resistant varieties when possible. Ensure proper drainage and avoid overhead watering. Remove and destroy infected plants. Sterilize tools between plants.

Uses

🍳

Fresh and Cooked Dishes

Culinary

Long Red Cayenne peppers can be used fresh in salsas, stir-fries, and hot sauces, or roasted and stuffed. They add moderate to high heat and fruity flavor to any dish. [source]

🍳

Cayenne Powder and Dried Spice

Culinary

Fully mature red peppers are dried and ground into the popular spice cayenne, used extensively in Creole, Mexican, and Asian cuisines for both flavor and heat. [source]

💊

Anti-inflammatory and Circulatory Support

Medicinal

Cayenne contains capsaicin, which has been traditionally used to reduce inflammation, improve circulation, and provide pain relief. Modern research supports its use in topical creams and dietary supplements. [source]

🏠

Natural Pest Deterrent

Harvest Tips

Harvest peppers when green for mild flavor, or allow 2-3 weeks longer to turn fully red for maximum heat and sweetness. Cut peppers with pruning shears rather than pulling to avoid damaging branches. Peppers can be harvested continuously throughout the season. For drying and cayenne powder, harvest when fully red and mature. Fruits can be stored in cool conditions for 2-3 weeks; freeze or dry for longer storage.

Fun Facts

  • 🌱 Long Red Cayenne peppers are named after the city of Cayenne in French Guiana, a historic center of spice trade, though the peppers likely originated in central Mexico.
  • 🌱 Capsaicin, the compound responsible for the heat in cayenne peppers, is the same substance used in wildlife deterrent sprays and pain-relief creams, and it actually tricks your brain into sensing heat without raising temperature.
  • 🌱 A single Long Red Cayenne plant can produce 50-100+ peppers over a growing season in optimal conditions, and in warm climates they can be grown as perennials, producing for several years.
