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.

Allium Tall 'Nectaroscordum'

Bulgaricum

Sometimes referred to as Allium bulgaricum, Nectaroscordum reaches 30 to 40 inches tall, featuring bell-shaped cream-colored flowers with maroon streaks and green-tinted bases. Blooming in late spring to early summer, its gracefully drooping florets later turn upright as they form decorative seed pods. Thriving in part shade to full sun and well-drained soil, it is drought-tolerant, deer-resistant, and attracts pollinators. Its twisted blue-gray foliage adds unique texture to borders and woodland plantings. Native to regions around the Mediterranean, it has been cultivated as both an ornamental and a culinary herb.

Growing and Maintenance Tips for Allium Tall 'Nectaroscordum'

Timing: Plant in fall before the ground freezes to ensure proper root development. Ideal soil temperature for planting is 60°F or colder.
Location: Choose a sunny, well-drained spot—poor drainage can cause bulb rot.
Depth & Spacing: Bury bulbs two to three times their height and space them six to twelve inches apart for optimal growth.
Soil: Maintain a pH of 6 to 7 and enrich with organic matter for better drainage.
Watering: Keep soil moist but not soggy during initial growth; once established, alliums are drought-tolerant.
Foliage Management: Leaves yellow after blooming—plant among perennials to disguise fading foliage.
Deadheading: Remove spent flowers to prevent self-seeding unless you want naturalized clusters.
Fertilization: Apply a balanced fertilizer in early spring to support strong blooms.
Pest & Disease Resistance: Alliums are deer and rabbit resistant but avoid planting in areas with excessive moisture to prevent fungal issues.
Crop Rotation: Change planting locations yearly to prevent soil-borne diseases.
