I am a landscape designer and have been purchasing 1000's of spring flowering bulbs from A.D.R. Bulbs for 100's of clients in the last 20 years. The bulbs have always been of top quality and if there were any problems, they have been quick to rectify. My orders are often complicated with many varieties and different amounts and they have always filled and delivered everything on time with the best customer care and attention to detail. The pictures in their catalog and website are beautiful. I have visited their facility in NY and was impressed with all their handling equipment and organization. I would highly recommend A.D.R. Bulbs to anyone in the wholesale trade who wants to purchase quality bulbs and work with genuinely nice people.

Growing and Maintenance Tips for Hyacinthus Orientalis 'Rainbow Mixture'

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.
