Seedling
4-6 weeksTiny seedlings with first true leaves appearing; very delicate and slow-growing initially
Start indoors 8-10 weeks before last frost. Maintain soil moisture and provide bright, indirect light. Keep temperatures at 65-70°F. Handle gently as seedlings are fragile. Ensure excellent air circulation to prevent damping off.
Vegetative Growth
3-4 weeksPlant develops multiple stems and lacy, deeply serrated green leaves; increasing in height and bushiness
Transplant outdoors after last frost when soil is warm. Pinch growing tips when 3-4 inches tall to encourage bushier, more compact growth. Gradually harden off seedlings. Apply balanced fertilizer every 3-4 weeks.
Budding
2-3 weeksFlower buds begin forming at branch tips; buds gradually enlarge and develop distinctive veining
Maintain consistent moisture and warmth (70-75°F ideal). Begin weekly fertilizer applications with slightly higher phosphorus to support blooming. Support stems if necessary as flowers are heavy. Ensure adequate air circulation.
Flowering
6-12 weeksElegant trumpet-shaped flowers with velvety texture and intricate throat markings open in succession
Deadhead spent flowers regularly to extend blooming season. Water consistently as heat can cause flowers to fade. Provide stakes or grow through netting for support. Maintain regular feeding schedule. Enjoy peak color in cooler temperatures.
Seed Production (optional)
3-4 weeksFlowers fade and develop seed pods; plant energy shifts from flowering to seed maturation
To save seeds, allow a few flowers to remain on the plant after blooming. Allow seed pods to dry on the plant, then collect and store in cool, dry place. For continuous flowers, deadhead regularly to prevent seed formation.

Plant flowers off as they fade to extend blooming from mid-summer through fall.
