Seed & Germination
7-14 daysSeeds are small and tan-colored. Germination occurs in 7-14 days under warm conditions (75-85°F).
Start seeds indoors 6-8 weeks before last frost. Use heat mat to maintain warmth. Keep soil moist but not soggy; provide bright light after sprouting.
Seedling
3-4 weeksTwo seed leaves (cotyledons) emerge, followed by true leaves. Seedlings are delicate and small.
Provide bright grow lights 14-16 hours daily. Keep soil moist. Thin or transplant to individual containers when second set of true leaves appears. Maintain warm temperatures (70-75°F).
Vegetative Growth
4-6 weeks (indoors); 2-3 weeks after transplanting outdoorsCompact, bushy plant develops multiple stems and glossy green foliage. Plant is 8-12 inches tall before flowering begins.
Gradually acclimate to outdoor conditions (hardening off) over 7-10 days before transplanting. Feed with balanced fertilizer every 2 weeks. Pinch growing tips if desired to encourage bushiness.
Flowering & Fruiting
8-12 weeks of continuous productionSmall white flowers appear at leaf nodes. Flowers mature into pea-sized green peppers that ripen through yellow, orange, red, and purple stages simultaneously on the same plant.
Maintain consistent watering and full sun. Switch to lower-nitrogen fertilizer (higher K and P) to support fruiting. Gently shake plant when flowering to aid pollination. Peppers may drop if stressed by temperature extremes or drought.
Peak Maturity & Harvest
Until first frost (or year-round in warm climates)Plant is laden with fruits in various color stages, creating a stunning multi-colored display. Fruits remain ornamental and edible until heavy frost.
Continue watering and feeding. Harvest peppers at any color stage—they are mildest at yellow/orange and progressively hotter at red/purple. Remove ripe peppers to encourage further flowering.

Harvest Tips
Peppers can be harvested at any color stage—they taste mildest at yellow/orange and gradually increase in heat as they ripen to red and purple. Snip peppers off with pruners rather than pulling to avoid damaging the plant. Harvest regularly to encourage continuous flowering. Peppers are fully ripe 60-90 days after transplanting, with production continuing until frost.
