Dormancy & Chilling
12-16 weeksBulbs are planted in fall and require 12-16 weeks of cold temperatures (32-55°F) to initiate flowering
Plant bulbs in October-November in most regions; ensure soil doesn't freeze solid around bulb. Mulch lightly with straw or leaves for insulation.
Emergence
2-3 weeksGreen shoots push through soil as temperatures warm in late winter/early spring
Remove mulch once shoots appear. Ensure adequate drainage. Begin regular watering if soil is dry.
Vegetative Growth
3-4 weeksStrap-like foliage emerges and grows; flower buds form within the plant
Water consistently. Apply balanced fertilizer (10-10-10) at emergence and again as buds form. Keep weeds clear.
Flowering
2-3 weeksDense flower spike emerges with dozens of small, fragrant star-shaped blue florets that open progressively from bottom to top
Stake if needed in windy locations. Deadhead individual spent flowers if desired, but leave stem until it yellows naturally. Provide consistent moisture.
Decline & Dormancy
6-8 weeksFlowers fade; foliage yellows and dies back; bulb enters dormancy
Allow foliage to remain green for 6 weeks after bloom to replenish bulb reserves. Reduce watering. Do not remove leaves until fully yellow. Allow soil to dry out in summer.
