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.
