Dormancy
12-15 weeksBulb lies dormant underground through fall and early winter, requiring cold period (vernalization) of 12-15 weeks below 45°F
Plant bulbs in fall (September-November). Ensure good drainage to prevent rot. No watering needed during dormancy.
Emergence & Growth
3-4 weeksThin, grass-like green foliage emerges from the soil as temperatures warm in late winter
Minimal intervention needed. Plant growth is driven by lengthening days and warming soil. No fertilizer required if soil is adequate.
Flowering
2-3 weeksDelicate violet-purple flowers with bright orange-yellow stamens open in late winter to early spring, typically February-March in northern zones
Flowers are cold-tolerant and may close during snow or frost. Protect from slug and snail damage. Allow flowers to remain on plant.
Seed Development & Foliage Maturation
4-6 weeksFlowers fade and foliage continues to photosynthesize, allowing bulb to store energy for next season
Do NOT cut or mow foliage. Allow leaves to yellow and die back naturally (4-6 weeks). This is critical for bulb vigor and naturalization.
Senescence & Rest
5-7 monthsFoliage completely dies back, bulb enters dormancy for summer and fall months
Reduce watering. Foliage may be removed once fully brown and papery. Bulbs require dry summer conditions to thrive.
