Dormancy/Root Development
Fall through early spring (3-4 months)Bulbs are planted in fall and develop roots over winter months while chilling requirements are met.
Plant bulbs 2-3 inches deep in loose soil. Ensure good drainage to prevent rot. No watering needed after initial planting unless conditions are extremely dry.
Emergence
2-3 weeks in early springGreen shoots and first leaves emerge as soil warms in early spring, typically 2-4 inches tall.
Keep mulch layer light to allow shoots to penetrate. Watch for slugs and snails on young foliage. Monitor for excessive moisture.
Flowering
2-4 weeks (March-April depending on zone)Plants produce 4-8 inch tall stems with clustered star-shaped blue flowers with white centers, each stem bearing 5-10 blooms.
Deadhead spent flowers if desired (optional; they self-seed readily). Provide light feeding with bulb fertilizer. Ensure adequate moisture during bloom.
Foliage Maturation
3-4 weeksAfter flowering, plants continue to develop foliage and build energy reserves in the bulb for next season.
Allow leaves to remain green and photosynthetically active; do not cut back. Reduce watering gradually as foliage matures. Continue light feeding with low-nitrogen fertilizer.
Senescence/Dormancy
3-4 weeks; then dormancy through summer and fallFoliage yellows and dies back completely; bulb enters summer dormancy underground.
Allow foliage to die back naturally; do not remove until fully brown. Stop watering. Bulbs need cool, dry period for proper chilling. Foliage typically disappears by early summer.
