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!

Hyacinthoides hispanica 'Blue', commonly known as Spanish Bluebells, reaches 12 to 18 inches tall, featuring graceful, bell-shaped blooms in soft lavender-blue. Each sturdy stem holds multiple nodding flowers, creating a charming woodland effect in spring. The strap-shaped foliage adds lush texture, complementing the delicate floral display.
Ideal for naturalizing in woodlands, borders, and under deciduous trees, this variety thrives in full sun to part shade and prefers moist, well-drained soil. It is deer-resistant and low-maintenance, returning reliably year after year for an effortless seasonal show.
Planting: Plant bulbs in fall, 4 inches deep and 4 to 6 inches apart. Position with the pointed end up. For naturalized drifts, scatter bulbs and plant where they fall.
Location: Partial to full shade is ideal—perfect under deciduous trees or in woodland-style gardens.
Soil: Moist, well-drained, humus-rich soil with a neutral to slightly acidic pH (6.0–7.0). Enrich with compost or leaf mold.
Watering: Keep soil moist during active growth in spring. Once foliage dies back, reduce watering—bulbs prefer dry summer dormancy.
Temperature: Hardy in USDA zones 4–9. Requires a cold period to bloom reliably.
Fertilization: Apply compost or a balanced fertilizer in early spring as shoots emerge.
Pruning: Allow foliage to die back naturally to feed the bulb. Remove spent flower stalks for tidiness.
Propagation: Naturalizes by offsets and self-seeding. Divide clumps in summer when dormant if needed.
Pest & Disease: Generally pest-free. Avoid overly wet conditions to prevent bulb rot.
