Dormancy/Planting
2-4 weeksBulbs are either dormant or recently planted with minimal visible growth
Plant bulbs in spring after last frost or indoors in containers. Store dry bulbs in cool, dark place if not planting immediately. Water sparingly until growth begins.
Vegetative Growth
3-4 weeksThin, grass-like green foliage emerges from soil, reaching 6-12 inches tall
Water moderately as foliage develops. Apply balanced fertilizer monthly. Ensure excellent drainage. Mulch lightly around bulbs.
Bud Formation
1-2 weeksFlower buds appear at stem tips, initially green and tightly closed
Continue consistent watering; rain or increased moisture triggers flowering. Maintain full sun exposure. Avoid overhead watering which can damage emerging buds.
Blooming
4-8 weeks (staggered blooms)Bright yellow star-shaped flowers open in morning and often close by evening; flowers are 1-2 inches across
Water consistently to keep successive blooms coming. Deadhead spent flowers to encourage repeat blooming. Protect from harsh winds. Each flower lasts 1 day but buds open sequentially.
Seed Development & Dormancy
4-8 weeksFlowers fade and seed pods develop; foliage gradually yellows and dies back in autumn
Allow foliage to die back naturally as it sends energy back to bulb. Reduce watering. Remove dead foliage when fully brown. Store bulbs dry in cool location or leave in soil if in warm climates.

Harvest Tips
These are ornamental flowers meant for display rather than harvest. Enjoy blooms in garden or cut individual flowers in early morning for indoor arrangements; they typically close by afternoon. Cut foliage only after natural senescence to allow bulb maturation. Collect seed pods if you wish to propagate from seed, though bulb division is faster.
Fun Facts
- 🌱 The genus name 'Zephyranthes' means 'flower of the west wind' in Greek, and the common name 'Rain Lily' refers to how these bulbs reliably flower shortly after summer rains, making them popular in warm, dry climates.
- 🌱 Unlike most lilies, Zephyranthes flowers are ephemeral—each bloom lasts only about 12 hours, opening in morning light and closing by evening, yet the plant produces successive blooms for weeks.
- 🌱 Zephyranthes citrina is native to Mexico and is one of the few yellow-flowering species in the genus; most Zephyranthes produce pink, white, or red flowers, making the yellow variety particularly prized among collectors.
