I have worked with A.D.R. Bulbs for almost 5 years now, and my company has sourced bulbs with them for longer than that. Communication is great - from ordering, to deliveries, to follow-ups on final product. I love the quality of the product as well as the service. We plant nearly 100,000 bulbs and A.D.R. keeps the whole process easy for us!

Hyacinthus orientalis 'Blue Jacket' reaches 8 to 12 inches tall, featuring dense spikes of deep porcelain-blue florets with a dark amethyst stripe on each petal. Its silvery edges add dimension, creating a striking mid-spring display. The sweet fragrance attracts bees and butterflies, making it a valuable early-season nectar source. Ideal for full sun to part shade, this variety thrives in well-drained soil and is deer-resistant.
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.
