Bulb Dormancy & Chilling
5-6 monthsBulbs require cold stratification over summer dormancy; stored dry in cool conditions
Plant bulbs in fall (October-November) after summer rest; keep completely dry during summer months; temperature fluctuation aids blooming readiness
Germination & Early Growth
4-6 weeksFirst shoots emerge in late fall; delicate grass-like foliage develops
Provide light watering as shoots emerge; ensure sharp drainage; protect from excessive moisture and fungal issues; minimal fertilizer needed
Vegetative Growth
6-8 weeksNarrow, slender leaves grow 6-12 inches tall; plant builds energy reserves
Maintain moderate moisture during winter-spring growing season; provide full sun exposure; avoid overfeeding which can reduce flowering
Flowering
2-4 weeksElegant cup-shaped flowers bloom on thin stems; petals display intricate spots and hairy texture; blooms last 1-2 weeks per flower
Reduce watering as flowers appear; protect from strong winds that may damage delicate stems; allow bees and butterflies to pollinate; avoid fertilizing during bloom
Seed Maturation & Dormancy
4-6 weeks to full dormancyFlowers fade and seed pods develop; foliage yellows and dies back; bulb enters dormancy
Allow foliage to fully die back naturally before removing; keep completely dry during summer dormancy; do not water; seed pods can be collected for propagation
