Dormancy Break & Root Development
2-3 weeksBulbs begin to sprout roots and show emergence of narrow, spotted or mottled leaves
Plant in fall (August-September). Water lightly after planting. Keep temperature cool (50-60°F) to trigger blooming. Ensure good drainage.
Vegetative Growth
4-6 weeksStrap-like leaves elongate, often with attractive burgundy or purple spotting or mottling
Increase watering as growth continues. Provide bright light indoors (south or west-facing window). Cool conditions (50-65°F) support robust foliage. Feed lightly with balanced or low-nitrogen fertilizer.
Bud Formation & Spike Elongation
2-3 weeksCentral flowering stem emerges with densely packed flower buds forming along the spike
Maintain cool temperatures and consistent moisture. Provide maximum light. Avoid moving pots excessively, which can stress buds.
Flowering
3-4 weeksDense spikes of tubular flowers open, displaying golden-yellow, red, and purple tones in a striking multicolored pattern
Keep soil evenly moist but not waterlogged. Cool rooms (50-60°F) extend flowering. Deadhead spent flowers to encourage bloom continuation. Provide bright light.
Post-Bloom & Dormancy Preparation
