Through the years I've tried just about everyone for bulbs but A.D.R. is tops. It's a family run business and the service levels and expertise are as good as the product they sell. My clients rave about the results we get with A.D.R. and that makes me happy.

Growing and Maintenance Tips for Hyacinthus Orientalis 'Delft Blue'

Planting: Plant bulbs in fall, 4 to 6 inches deep and 4 to 6 inches apart, with the pointed end facing up. For best results, plant in groups for maximum fragrance and visual impact.
Location: Full sun to partial shade. Choose a spot with good air circulation to prevent disease.
Soil: Moist but well-drained, slightly acidic to neutral soil (pH 6.0–7.0). Avoid heavy clay—amend with compost or sand if needed.
Watering: Water after planting, then only during dry spells. Avoid overwatering—bulbs are prone to rot in soggy soil.
Temperature: Hardy in USDA zones 4–8. Requires 10–14 weeks of cold to bloom reliably.
Fertilization: Apply a balanced fertilizer at planting and again in early spring as shoots emerge.
Pruning: Remove spent flower spikes after blooming. Allow foliage to die back naturally to feed the bulb.
Propagation: Naturalizes slowly by offsets. Lift and divide clumps every few years in summer when dormant.
Pest & Disease: Generally pest-free. Bulbs are toxic to rodents and deer, but wear gloves—handling may cause skin irritation.
