Dormancy & Chilling
3-4 monthsBulbs are planted in autumn and undergo cold stratification over winter; no visible growth above ground
Plant in well-draining soil in October-November; protect from excessive moisture; ensure 12-16 weeks of cold (below 45°F)
Emergence
2-3 weeksGrass-like foliage emerges as soil warms in early spring; thin, upright leaves appear first
Reduce watering; monitor for slugs and snails; ensure good air circulation
Flowering
2-3 weeksDelicate pale yellow flowers with orchid-like form appear on short stems (6-12 inches tall); fragrant blooms with upright petals and drooping falls
Do not overwater; provide full sun exposure; protect from strong winds; enjoy fragrance
Seed Set & Foliage Maturation
3-4 weeksAfter flowering, foliage continues growing and accumulating energy for next year; seed pods may develop if pollinated
Allow foliage to remain until it yellows naturally; continue light watering; deadhead spent flowers unless collecting seed
Dormancy Preparation
4-6 monthsFoliage yellows and dies back; plant enters summer dormancy; bulb stores energy underground
Gradually reduce watering; withhold water during dormancy; protect from summer heat and moisture; mulch lightly
