Narcissi Double 'Obdam'
Daffodil
Narcissus 'Obdam' is a double daffodil, reaching 14 to 18 inches in height. It produces large, creamy-white blooms with soft yellow centers that gradually fade to pure white, creating an elegant, layered effect. The flowers appear in mid-to-late spring and are sweetly fragrant, making them excellent for cut arrangements. Thriving in full sun to part shade, 'Obdam' prefers well-drained soil and is deer-resistant, rabbit-resistant, and drought-tolerant.

Growing and Maintenance Tips for Narcissi Double 'Obdam'
Planting: Plant bulbs in fall, 6 inches deep and 4 to 6 inches apart, with the pointed end up. Choose a sheltered spot—double blooms are heavier and benefit from wind protection.
Location: Full sun to partial shade. At least 6 hours of sunlight daily ensures strong stems and vibrant blooms.
Soil: Well-drained, fertile loam with a pH of 6.0–7.0. Enrich with compost or peat moss to improve drainage and structure.
Watering: Water after planting and during active spring growth. Reduce watering once foliage yellows—bulbs prefer dry summer dormancy.
Temperature: Hardy in USDA zones 3–9. Requires a winter chill to bloom reliably.
Fertilization: Apply compost or a balanced, low-nitrogen fertilizer in fall and again in early spring.
Pruning: Deadhead spent blooms to prevent seed formation. Allow foliage to die back naturally to recharge the bulb.
Propagation: Naturalizes by offsets. Divide clumps every 4 to 5 years in summer when dormant.
