Dormancy & Planting
Planting through winter dormancyBulbs are planted in fall (September-November) or early spring. The bulb is firm and papery with a pointed top and basal roots.
Plant in well-draining soil, pointed end up. Plant 8-10 inches deep to protect from cold and prevent splitting. Mulch after planting in cold climates.
Shoot Emergence & Vegetative Growth
4-6 weeks in springGreen shoots emerge in spring, growing rapidly into tall stems with narrow, lanceolate leaves arranged alternately along the stem.
Ensure consistent moisture. Apply balanced fertilizer when shoots are 4-6 inches tall. Stake tall varieties for support. Keep area weed-free.
Bud Formation
2-3 weeksTerminal buds form at stem tips, initially small and green, gradually swelling as flower petals develop inside the papery bud covering.
Continue regular watering. Apply low-nitrogen, high-phosphorus fertilizer to encourage blooming. Remove any diseased leaves. Provide support stakes if needed.
Flowering
3-4 weeksBuds open into large, fragrant white trumpet flowers with prominent golden stamens. Blooms typically open from the bottom of the cluster upward, with multiple flowers per bulb.
Remove stamens if not desired (reduces pollen staining). Deadhead spent flowers but leave stem and leaves. Continue watering at soil level. Enjoy the intense fragrance.
Post-Flowering & Dormancy
6-10 weeksFlowers fade; stems remain green with leaves still photosynthesizing. Eventually, foliage yellows and dies back completely as the bulb enters dormancy.
Do NOT cut down stems until completely brown and dried (6-8 weeks after flowering). Continue watering to rebuild bulb reserves. Apply low-nitrogen fertilizer. Remove foliage once fully dead.

Harvest Tips
Cut stems in early morning when flowers are just opening for longest vase life. Use a sharp knife, cutting low on the stem but leaving at least 2-3 leaf nodes on the plant to continue feeding the bulb. Remove lower leaves that would sit below the water line. Change water every 2-3 days and re-cut stem ends. Casablanca lilies last 10-14 days in a vase.
Fun Facts
- 🌱 Casablanca lilies are Oriental hybrids created by selective breeding; the name references the city of Casablanca, Morocco, though the variety was developed in Asia.
- 🌱 A single lily bulb can produce 8-12 flowers per stem, and mature plants often develop multiple stems, creating an explosion of blooms in mid to late summer.
- 🌱 The pollen of Casablanca lilies is notoriously staining; florists often remove stamens (the pollen-bearing anthers) before sale to protect furniture and clothing, and the flowers still retain their fragrance.
