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.

Tulipa Darwin Hybrid 'Ad Rem'
Tulip
Ad Rem is a Darwin Hybrid tulip known for its rich, deep-orange petals edged with a fine golden band. Its sturdy stems reach approximately 22 to 24 inches tall, supporting large, cup-shaped blooms that can span up to 6 inches across when fully open. Blooming in mid to late spring, it thrives in full sun and well-drained soil, making it an excellent choice for borders, mass plantings, and cut arrangements.
Introduced in 1960, Ad Rem—like many Darwin Hybrids—is a sport of the classic Apeldoorn cultivar.

Growing and Maintenance Tips for Tulipa Darwin Hybrid 'Ad Rem'
Planting: Plant in fall when soil temperatures drop below 55°F. Set bulbs 6–8 inches deep with the pointed end up. Darwin Hybrids are ideal for large-scale displays, perennial borders, and cutting gardens due to their impressive size and vigor.
Spacing: Space bulbs 4–6 inches apart. For maximum impact, plant in groups of 10 or more—tall stems and broad flowers are especially striking in mass.
Light: Full sun is essential for strong stems and rich bloom color. While light shade is tolerated, abundant light ensures upright growth and long-lasting flowers.
Soil: Provide well-drained, neutral to slightly acidic soil (pH 6–7). Avoid poorly drained areas—these large bulbs are prone to rot in wet spring conditions.
Watering: Water after planting to settle the soil. In spring, water only during extended dry periods to preserve bloom integrity.
Temperature & Dormancy: Requires 12–16 weeks of cold (below 50°F) for proper root formation and bloom development.
Fertilization: Apply balanced bulb fertilizer when planting and again in early spring as foliage appears. This supports their strong perennial tendencies and bold floral performance.
Pests: Squirrels may dig newly planted bulbs—protect with mulch or mesh. Deer will eat buds and foliage, especially early in spring, so use repellents or fencing in high-pressure areas.
Disease: To prevent Botrytis (Tulip Fire), plant only healthy, firm bulbs in sunny, well-ventilated locations. Avoid overhead watering and promptly remove any infected tissue—do not compost. Rotate planting sites annually and avoid replanting in previously affected areas for three years.
