Capsicum chinense

vegetable

Trinidad Scotch Bonnet is an extremely hot chili pepper variety originating from Trinidad and Tobago, known for its distinctive lantern-shaped pods and intense fruity heat. Peppers mature from green to bright red-orange and pack 100,000-350,000 Scoville Heat Units (SHU), making them significantly hotter than jalapeños. This ornamental yet productive plant produces abundant yields over a long growing season.

Growth Stages

1

Seedling

2-3 weeks

Tiny leaves emerge, plant is 1-3 inches tall with first true leaves appearing

Keep soil moist but not waterlogged. Provide bright light (12-14 hours under grow lights). Maintain 75-85°F. Thin to strongest seedling if multiple sprouts.

2

Vegetative

4-6 weeks

Plant develops multiple sets of leaves, branching structure forms, 4-12 inches tall

Transplant to larger pots or garden when 3-4 inches tall. Maintain consistent warmth (70-80°F). Begin weekly fertilizer diluted to half strength. Pinch off early flowers to promote branching.

3

Flowering

4-8 weeks

Small white, occasionally purple-tinged flowers appear in leaf axils; plant is 12-24+ inches tall

Reduce nitrogen, increase phosphorus/potassium to support fruiting. Ensure consistent watering and 8+ hours of sunlight. Hand-pollinate flowers with small brush if indoors or in low-pollinator areas. Mulch around base to retain moisture.

4

Fruiting

6-10 weeks per fruit

Green lantern-shaped peppers develop, gradually enlarge to 1-1.5 inches, transition from green to red-orange

Continue consistent watering and fertilizing every 2-3 weeks. Support branches with stakes if heavily laden with fruit. Full maturity to bright red-orange indicates maximum heat and flavor. Peppers are edible at green stage but hotter when fully ripe.

5

Harvest

Ongoing through season

Peppers reach full red-orange color, slightly soft to slight firmness, fully mature

Harvest ripe peppers using pruning shears to avoid damaging plant. Removing peppers encourages continued production. Plant may produce for 6+ months in warm climates or until frost.

Harvest Tips

Harvest peppers when they reach full red-orange color (typically 60-90 days after flowering) using clean pruning shears or scissors. Peppers are hottest and most flavorful when fully mature and ripe. Wear gloves when handling and wash hands thoroughly before touching face. Green peppers are edible but milder; allow them to ripen for maximum heat. Consistent harvesting encourages continued fruit production throughout the season.
