Dormancy
3-4 monthsBulb lies dormant in soil over winter, developing roots in fall and early winter
Plant bulbs in autumn (September-November). Ensure good drainage to prevent rot. Mulch lightly with organic matter for insulation.
Emergence
2-3 weeksNarrow, grass-like foliage emerges from soil in early spring as temperatures warm
No special care needed. Remove winter mulch as shoots emerge. Protect from late frosts if necessary in colder zones.
Flowering
2-3 weeksShort stems produce clusters of pale blue star-shaped flowers with darker blue stripes, typically 4-8 inches tall
Maintain consistent soil moisture during flowering. Deadhead spent flowers if desired, though fruit formation is minimal. Enjoy blooms for 2-3 weeks.
Post-Bloom
3-4 weeksFoliage remains after flowers fade, continuing to photosynthesize and rebuild bulb reserves
Allow foliage to die back naturally before removing. Continue watering moderately until leaves yellow. Do not remove leaves prematurely.
Dormancy
5-6 monthsPlant enters summer dormancy as foliage withers and bulb consolidates energy for next season
Reduce watering significantly. Mark planting location to avoid accidental disturbance. Bulbs require cool dormant period for next year's bloom.
