Growth Stages

1

Dormancy & Planting

Varies with climate; cold treatment requires 12-16 weeks

Bulbs are dormant and require cold period. Plant in fall (September-November) or early spring for best results.

Choose firm, healthy bulbs. Ensure excellent drainage to prevent rot. Mulch lightly if planting in fall. Provide chilling period of 12+ weeks in zones above 8.

2

Emergence & Vegetative Growth

4-6 weeks

Shoots emerge and develop 6-8 narrow, lance-shaped leaves. Stems grow rapidly, reaching 2-3 feet tall.

Water regularly as growth accelerates. Apply balanced fertilizer once shoots are 6 inches tall. Support tall varieties with stakes if needed. Remove any diseased foliage promptly.

3

Bud Formation & Development

3-4 weeks

Terminal buds appear at stem tips, forming clusters of 4-8 large buds. Buds gradually swell and color develops.

Switch to higher phosphorus fertilizer to encourage blooming. Continue consistent watering. Stake stems if needed to prevent wind damage. Remove lower leaves to improve air circulation.

4

Flowering

2-4 weeks per spike (varies with weather)

Large, deep red fragrant flowers open sequentially from bottom to top of the cluster. Each flower is 6-8 inches across with ruffled petals and golden stamens.

Deadhead spent flowers to extend bloom period (leave lowest flowers to mature for seed development if desired). Avoid overhead watering. Cut flowers in early morning for longevity. Enjoy fragrance—these lilies are strongly scented.

5

Post-Flowering & Bulb Ripening

6-8 weeks

Petals drop and seed pods form. Foliage remains green and continues photosynthesis to replenish bulb reserves.

Do NOT cut foliage until it dies back naturally (at least 6 weeks post-bloom). Continue watering and fertilizing with low-nitrogen formula. Allow pods to mature if saving seed. Stop watering once foliage browns completely.

Common Pests

  • Hand-pick red beetles and orange larvae daily. Remove debris where they overwinter. Use neem oil or spinosad spray as needed. Encourage natural predators.

  • Spray with strong water stream to dislodge. Use insecticidal soap or neem oil. Encourage ladybugs and parasitic wasps.

  • Increase humidity by misting foliage (do so in morning). Use miticide if severe. Ensure good air circulation.

  • Remove damaged flowers promptly. Use blue sticky traps. Apply spinosad or insecticidal soap if populations are heavy.

  • and

    Improve air circulation by removing lower foliage. Water at soil level only, not on leaves. Remove infected foliage. Apply sulfur or copper fungicide preventatively in humid conditions.

  • Plant in extremely well-draining soil. Avoid waterlogging. Ensure proper spacing for air circulation. Lift and replant bulbs in new location if drainage is poor.

Harvest Tips

Cut flowers in early morning when first or second flower on the spike is opening. Use a sharp knife to cut stems at a 45-degree angle. Remove lower leaves that would sit below the water line in the vase. Change water every 2-3 days. Lilies last 1-2 weeks in a vase. For garden display, deadhead spent flowers but allow at least the lowest flowers to set seed and persist on the plant. Do not cut stems below the top 1/3 of the plant, as foliage is needed for bulb replenishment.

Fun Facts

  • 🌱 The name 'Sorbonne' honors the historic University of Paris, reflecting this cultivar's sophistication and prestige in the horticultural world.
