Frosty Fire is an ornamental pepper variety prized for its striking bicolor fruits that transition from cream and purple to red as they mature. These compact plants produce abundant small, upright peppers that are both decorative and edible, making them ideal for containers and garden borders. The plant is valued as much for its ornamental appeal as for its mild pepper flavor.

Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with seed leaves (cotyledons) emerge; first true leaves appear within 1-2 weeks

Keep soil warm (75-85°F), moist but not waterlogged. Provide bright light; use grow lights if needed. Thin to strongest seedling per cell

2

Vegetative

6-8 weeks indoors; 2-3 weeks after transplanting

Plant develops multiple sets of true leaves and a compact, bushy structure. Stems thicken and branching increases

Maintain warm temperatures (70-80°F day, 60-70°F night). Harden off before transplanting. Fertilize every 2 weeks with balanced fertilizer

3

Flowering

3-4 weeks

Small white flowers appear at branch junctions. Plant becomes increasingly dense and decorative

Ensure adequate light and consistent watering. Use phosphorus-rich fertilizer to promote flowering. Maintain temperatures 65-80°F for best pollination

4

Fruiting & Color Development

4-6 weeks per fruit cycle

Peppers develop and change color through cream, purple, and orange stages before turning deep red. Multiple fruits mature simultaneously

Reduce nitrogen fertilizer; maintain phosphorus and potassium. Water consistently. Support branches if heavily laden with fruit. Enjoy ornamental display

5

Harvest

Throughout growing season

Peppers reach full red color and can be harvested at any stage of ripeness

Pick peppers regularly to encourage continued production. Use scissors or pruners to avoid damaging plant. Peppers are ornamental at all color stages

Harvest Tips

Begin harvesting when peppers reach desired color stage (ornamental appeal at purple-orange stage; fully ripe at red). Peppers are edible at all stages. Use clean scissors or pruners to cut stems rather than pulling. Harvest regularly to encourage continued flowering and fruiting throughout the season. Peppers can be left on plant to continue ripening for more intense red color.
