Dormancy & Chilling
8-16 weeksBulbs are dormant underground during summer and fall, requiring a cold period to trigger flowering
Plant bulbs in fall (September-November) in cold climates. Ensure bulbs receive 12-16 weeks of cold temperatures below 45°F for proper vernalization.
Sprouting
2-4 weeksGreen shoots emerge from the soil as soil temperatures warm in early spring
Maintain moderate moisture as growth begins. Apply a light layer of mulch to retain moisture and regulate soil temperature. Remove mulch once shoots are 1-2 inches tall.
Vegetative Growth
3-6 weeksLong, slender green leaves develop and elongate; plant establishes foliage structure
Water regularly during dry spells. Avoid overhead watering to prevent fungal issues. Apply balanced fertilizer (10-10-10) every 3-4 weeks.
Flowering
2-4 weeksClusters of small white star-shaped flowers with distinctive green stripes bloom on upright stems
Flowers typically open on sunny days and close at night. Deadhead spent flowers to encourage longer blooming. Provide water during dry periods.
Seed Development & Dormancy
4-8 weeksFlowers fade; seed capsules form if flowers are not deadheaded; foliage yellows and dies back naturally
Allow foliage to remain until it turns completely yellow and dies back naturally to allow bulb replenishment. Reduce watering gradually. Stop fertilizing.
