Seedling
3-4 weeksSmall plants with 2-4 true leaves, delicate appearance. Growth is slow initially as root system develops.
Keep soil consistently moist but not soggy. Maintain temperatures 70-80°F. Provide bright light 14-16 hours daily. Thin to strongest seedlings.
Vegetative
4-6 weeksPlant develops multiple branches, leaf nodes increase, stems thicken. Plant becomes bushy and compact.
Maintain warm temperatures (75-85°F). Fertilize weekly with balanced fertilizer. Pinch terminal buds to encourage branching. Ensure adequate light.
Flowering
3-4 weeksSmall white or light purple flowers appear at leaf axils. Flower clusters develop along branches.
Maintain consistent watering and temperatures. Switch to lower-nitrogen fertilizer (higher phosphorus and potassium). Avoid excessive nitrogen which reduces flowering. Ensure good air circulation.
Fruiting
4-6 weeksSmall green fruits develop from flowers, enlarging over time. Fruits transition from green to dark red as they mature.
Maintain even moisture; inconsistent watering causes fruit cracking and blossom end rot. Apply calcium supplement if needed. Support branches laden with fruit. Continue regular fertilization with fruit-promoting blend.
Harvest-Ready
Until frost or seasonal endFruits achieve full red color, become firm and thick-walled. Plant may be in continuous production.
Harvest regularly to encourage continued production. Use sharp shears to cut fruits. Can harvest green for milder flavor or allow full red color development for sweeter, more complex taste.

-
Use yellow sticky traps. Spray with insecticidal soap or neem oil. Encourage natural predators. Remove heavily infested leaves.
-
Remove and destroy infested fruits immediately. Use insecticides containing spinosad. Monitor closely in warmer zones where this pest is common. Practice crop rotation.

Uses
Roasting & Charring
CulinaryCimarron's thick walls and large size make it ideal for roasting whole over an open flame until charred, then peeling for use in salsas, soups, and regional dishes like chile relleno. [source]
Drying & Powder
CulinaryThe fruits dry well for making chile powder, crushed red pepper flakes, and dried chile infusions. Dried Cimarron peppers retain good flavor and heat for long-term storage. [source]
Fresh Cooking
CulinaryUse fresh in salsas, stir-fries, stuffing, and cooked vegetable dishes. The thick flesh holds up well to cooking without becoming mushy. [source]
Heat & Circulation Support
MedicinalChili peppers contain capsaicin, which may support circulation and metabolism. Traditionally used in folk medicine for pain relief and digestive support. [source]
Pepper Flakes & Seasoning

Harvest Tips
Harvest Cimarron peppers when they reach full red color for maximum sweetness and heat complexity (typically 75-90 days from transplant). Use sharp pruning shears or scissors to avoid damaging the plant. Peppers can be harvested earlier at green stage if preferred for milder flavor. Pick regularly to encourage continuous production throughout the season. Wear gloves if sensitive to capsaicin oils. Store harvested peppers in cool, humid conditions (50-60°F) for extended shelf life.
Fun Facts
- 🌱 The name 'Cimarron' refers to wild or untamed in Spanish, reflecting the pepper's origins in indigenous Latin American agriculture before domestication.
- 🌱 Cimarron peppers are heat-stable and improve in flavor when dried, with the drying process concentrating sugars and developing deeper, more complex notes.
- 🌱 The thick-walled variety makes Cimarron exceptional for roasting because the flesh chars beautifully while the interior steams, creating tender, peelable skin—a technique used extensively in New Mexican and Spanish cuisine.
