2-3 weeksGreen shoots emerge from soil after chilling period; first leaves appear pale green
Move to bright location (indoors or outdoors); maintain 60-70°F temperature; water gently
Vegetative Growth
2-3 weeksMultiple leaves develop, buds form at stem tips, plant reaches full foliage height
Ensure bright light, good air circulation; maintain consistent moisture; apply dilute liquid fertilizer
Flowering
2-4 weeksGolden buds open to reveal bright yellow trumpets surrounded by reflexed petals; flowers emit strong, sweet fragrance
Keep cooler (60-65°F if forcing indoors) to extend bloom; provide bright light; avoid drafts; enjoy fragrance

Harvest Tips
Cut flowers when buds show color but have not fully opened for longest vase life (7-10 days). Harvest in early morning. For naturalizing, allow flowers to fade naturally on plant and refrain from deadheading until foliage yellows. Do not cut foliage until 6+ weeks after flowering to allow bulb energy storage.
