Vegetative
3-4 weeksPlant develops multiple stems, darker purple-black leaves become prominent, bushy growth habit forms. No flowers yet.
Pinch off early flower buds to encourage branching. Apply balanced fertilizer every 2-3 weeks. Water consistently. Acclimate to outdoor conditions if grown indoors.
Flowering
2-3 weeksSmall white or pale purple flowers appear at branch tips, contrasting beautifully with dark foliage. Multiple flowers bloom simultaneously.

Harvest Tips
Harvest peppers at any stage—green peppers are milder and can be picked 60-70 days after transplanting, while red peppers (fully mature) develop fuller flavor and sweetness after 3-4 additional weeks. Use pruning shears or a sharp knife to cut peppers cleanly from the plant. Regular harvesting encourages continuous production. Peppers keep 1-2 weeks at room temperature or 2-3 weeks refrigerated.
