Reiman Gardens switched to A.D.R. Bulbs 12 years ago and has never looked back. The bulbs are high quality and the customer service is exceptional. Chris and Philipp are always willing to answer my many questions! We take pride in supporting one of the last remaining bulb farms that grows and exports.

Allium nigrum, also known as black garlic or broad-leaved leek, reaches 18 to 24 inches tall, featuring 3 to 4 inch flat clusters of creamy-white to pale lilac star-shaped florets with green centers. Blooming in late spring to early summer, it thrives in full sun and well-drained soil, showing drought tolerance and strong resistance to deer while attracting pollinators. Native to the Middle East, it has naturalized in parts of the United States. Ideal for borders and mixed plantings, it pairs beautifully with pink or white delphiniums, peonies, and irises.

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.
