We have been purchasing our bulbs from A.D.R. for many years now. As a contractor, the process to order bulbs for many different clients is easy and seamless. The website is a wonderful tool that we refer to quite often for product information, photos, and combination ideas. Our bulbs always arrive on time and wonderfully organized to make our installation much more efficient . The product is top notch and leaves our customers with wanting more and more each season.

Allium azureum, also known as caeruleum, reaches 18 to 32 inches tall, featuring 1.5-inch round flax-blue flower globes that bloom from late spring into early summer. Thriving in full sun and well-drained soil, it is drought-tolerant, deer-resistant, and attracts pollinators. Its slender stems and airy blooms create a delicate yet striking presence in borders, rock gardens, and mixed plantings.

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.
