Carolina Reaper

Capsicum chinense

Family: Solanaceae

The Carolina Reaper held the Guinness World Record for the world's hottest pepper, averaging over 1.6 million Scoville units with some peppers exceeding 2.2 million. Developed in South Carolina, these distinctive scorpion-tailed peppers deliver extreme heat with a surprisingly sweet, fruity flavor.

History & Nutrition

History

The Carolina Reaper was created by Ed Currie, founder of the PuckerButt Pepper Company in Fort Mill, South Carolina, through over a decade of selective breeding beginning around 2003. Currie crossed a Pakistani Naga pepper with a Red Habanero, then spent years stabilizing the variety and selecting for maximum heat. In November 2013, Guinness World Records certified the Carolina Reaper as the world's hottest pepper at an average of 1,569,300 Scoville Heat Units, with individual peppers testing as high as 2.2 million SHU. The pepper's distinctive appearance—bright red, gnarled, and wrinkled with a pointed "scorpion tail" stinger—makes it instantly recognizable. What surprised many was that beneath the extreme heat lies a genuinely pleasant flavor: fruity, almost citrusy sweetness that reveals itself once the initial burn subsides. Currie, a self-described "hot sauce alchemist," originally pursued superhot peppers not for bragging rights but because capsaicin research suggested potential health benefits, including cancer-fighting properties. The Reaper became a viral sensation, spawning countless YouTube challenge videos, hot sauce product lines, and even a medical case report after a man experienced "thunderclap headaches" from eating one. While newer peppers like Pepper X (also bred by Currie) have since claimed higher heat records, the Carolina Reaper remains the most famous superhot pepper and the benchmark against which all others are measured.

Climate & Temperature

Optimal Growing Temp

75°F - 95°F

The Carolina Reaper demands intense heat. Soil temps must reach 85-90°F for germination. Plants thrive in conditions other peppers find stressful.

Survival Range

60°F - 105°F

Can survive these temperatures

warm Season

Best USDA Zones

Zone 9Zone 10Zone 11

Humidity

50-70%

Tolerates humidity well but needs good air circulation. High humidity during flowering can reduce fruit set.

Plant Size & Growth

Height

3-5 feet

Spread

24-36 inches

Growth Habit

bush

annualRoot Depth: Deep, extensive root system 18-24 inches. Strong roots essential for supporting the extreme capsaicin production.
Growth Stages

Germination

14-35 days

Notoriously slow and inconsistent. Bottom heat (85-90°F) essential. Pre-soak seeds 12-24 hours. Patience required.

Seedling Stage

Duration: 6-8 weeks

True leaves: First true leaves appear 3-4 weeks after germination

Transplant ready: Ready when 4-6 inches tall. Extremely slow growth initially. Keep warm constantly.

Vegetative Growth

Duration: 8-12 weeks

Growth accelerates once plants establish. Feed regularly and maintain warmth.

Flowering

Timing: 10-14 weeks after transplant

Duration: 2-4 weeks

Self-pollinating. Night temps above 65°F essential for fruit set.

Fruit Development

Begins: 12-16 weeks after transplant

Duration: 5-7 weeks per wave

Peppers develop distinctive wrinkled, scorpion-tail appearance. Green to red color change.

Harvest Maturity

Timing: 120-150 days from transplant

  • Full bright red color throughout
  • Pronounced scorpion "tail" formed
  • Wrinkled, gnarled skin texture
  • Slight softening indicates peak ripeness
  • World's hottest pepper—handle with extreme care
Expected Yield

Per Plant

15-30 peppers per plant (fewer but hotter than most varieties)

Per Square Foot

8-15 peppers

Harvest Frequency

Multiple harvests over 8-10 weeks once fruiting begins

Factors Affecting Yield

  • •Extreme heat and long season essential
  • •Stress (water, heat) increases capsaicin dramatically
  • •One pepper provides extreme heat for multiple batches
  • •Quality over quantity with superhots
Watering Guide

Seedling Stage

Keep consistently moist, never waterlogged

Established Plants

Deep watering when top 2 inches dry

During Fruiting

Strategic stress increases capsaicin

Preferred Method

Drip irrigation or careful hand watering at base

⚠️ Critical Watering Periods

  • • Flowering needs consistent moisture
  • • Reduce (but don't eliminate) during final ripening for maximum heat

Pro Tips

  • PRO TIP: 10-14 days of reduced water before harvest dramatically increases heat levels
  • Morning watering only
  • Heavy mulch retains moisture and warmth
  • Never let plants dry completely—kills capsaicin production
