Rocoto Red
Capsicum pubescens — 100,000–250,000 SHU
Rocoto Red is a thick-walled, apple-shaped Andean pepper from the Capsicum pubescens species — the only major pepper family that thrives in cool conditions. Native to the Peruvian and Bolivian Andes at 2,000–3,000m altitude, it produces large, meaty red fruits with black seeds (unique among all cultivated peppers). The thick walls contain serious heat alongside genuine fruity flavour. It actually performs better in cool UK summers than in tropical heat.

🌱 How to Grow Rocoto Red
Uniquely tolerates and even prefers partial shade and cool temperatures — unlike any other hot pepper. Ideal for north-facing gardens and cool UK summers.
Prefers 12–20°C — the OPPOSITE of most peppers. Above 30°C, it stops fruiting. Native Andean habitat is cool mountain conditions, not tropical lowlands.
Thick-walled fruits need steady moisture. More forgiving of overwatering than most peppers — prefers moist conditions like its Andean mountain home.
20–25L pot or planted in the ground. A large, long-lived perennial shrub in its native range — give it room to grow.
Monthly balanced feed throughout the growing season. Less demanding than Chinense superhots — doesn't need heavy weekly feeding.
The most common mistake with Rocoto — bringing it into a warm greenhouse. It will drop all its flowers above 30°C. Keep it outside in UK summer conditions.
🩺 Common Problems
Cause: Temperatures above 28–30°C cause complete flower abortion — the opposite problem to most peppers
Fix: Move to shade during heatwaves, do NOT put in a greenhouse in summer. This pepper prefers outdoor UK temperatures.
Cause: Pubescens species is notoriously slow to germinate — often 4–8 weeks even with heat
Fix: Sow in December/January, heat mat at 28°C, perlite mix. Patience essential — do not discard after 3 weeks.
Cause: Rocoto grows slowly and invests heavily in its root system in year one
Fix: Overwinter as a perennial — year two and three plants are dramatically more productive
Cause: Normal Pubescens characteristic — anthocyanin pigments in foliage
Fix: Not a defect or disease — the purple tints in leaves are a characteristic of the Capsicum pubescens species
❓ Common Questions
What makes Rocoto different from other hot peppers?
It loves cool conditions — native to the Andes at 2,000–3,000m. It has black seeds (unique among cultivated peppers) and thick apple-like walls. Above 30°C, it drops all flowers.
How hot is Red Rocoto?
100,000–250,000 SHU — comparable to Habanero. The thick walls contain the heat, making it slightly less immediate than thin-walled peppers at similar SHU.
Can I grow Rocoto in the UK?
Rocoto actually prefers UK cool summers. It does NOT like temperatures above 30°C — one of the few hot peppers genuinely well-suited to outdoor British growing.
What does it taste like?
Rich, fruity, and complex — closer to an apple in texture due to thick walls, with significant heat. Used extensively in Peruvian cooking, stuffed and roasted.
