Plant Needs
Sunlight
Full sun to partial shade; full sun promotes the most abundant flowering, while partial shade is tolerated in warmer temperate regions
Watering
Water thoroughly during active growth and flowering; allow the top 2–3 cm of soil to dry slightly between waterings to prevent bulb rot
Temperature
Hardy to -15°C; requires cool, dry conditions during summer dormancy to protect bulbs from heat stress
Characteristics
- Leaf: Narrow, strap-shaped basal leaves, glossy green, emerging alongside flower stalks
- Flower: Star-shaped, pale to mid-blue blooms with white central stripes, borne in loose racemes
- Bulb: Small, ovoid underground bulb with papery brown tunic
Care Guide
Watering
Keep soil consistently moist during active growth and flowering period
Fertilization
Apply diluted balanced fertilizer once when foliage first emerges. Use low-nitrogen fertilizer to prioritize bulb development and flowering over foliage growth
Eggshell powder topdressing：Sprinkle a thin layer of crushed, dried eggshell powder around bulbs in early spring to boost soil calcium levels and improve drainagePruning
- Remove spent flower stalks after blooming to direct energy to bulb maturation
- Allow foliage to die back naturally before trimming to ensure the bulb stores sufficient nutrients for next year's growth
- Thin overcrowded bulbs every 3–4 years in late summer to maintain healthy clumping growth
