Dormancy & Chilling
12-16 weeksBulbs rest underground during winter, requiring 12-16 weeks of cold (below 45°F) to trigger flowering.
Plant bulbs in fall (September-November). Mulch lightly to insulate. Do not disturb.
Emergence & Growth
2-3 weeksDistinctive mottled leaves emerge in early spring, followed by flower buds rising above the foliage.
Remove mulch as shoots emerge. Ensure consistent moisture. Protect from late frost.
Flowering
2-3 weeksOne or two nodding, reflexed flowers per bulb, typically bicolored with purple-red outer petals and yellow inner petals with prominent stamens.
Do not remove flowers or foliage. Deadhead spent flowers only if desired. Keep soil moderately moist.
Post-Flowering & Leaf Maturation
3-4 weeksFlowers fade; foliage continues photosynthesizing to replenish bulb energy. Leaves may yellow and die back.
Continue watering until foliage naturally yellows. Do not cut leaves until completely dry. Allow self-seeding.
Summer Dormancy
5-7 monthsAbove-ground plant material disappears; bulb enters dormancy underground.
Reduce watering significantly. Mark planting locations to avoid disturbance. Allow soil to dry slightly.
