Allium Azureum Blue Globe Ornamental Onion Bulbs

Plant Allium Azureum Blue Globe ornamental onion bulbs before the first frost in fall, and early the next summer they produce 1½ pompom flower heads filled with small, star-shaped, true-blue blooms atop stiff stems rising to 20 inches tall. Gaining in popularity, allium flowers definitely have the "Wow!" factor and a thoroughly modern appeal. Azureum Blue Globe blooms attract pollinators to the garden, including butterflies, and make fabulous cut flowers for floral arrangements, fresh and dried.

An Allium caeruleum species, commonly called ornamental onion or blue globe onion, Azureum, a Siberian native, is bulbous perennial with an upright habit. Alliums are in the same family as garlic, onions, chives, and shallots, but ornamental alliums have beautiful blooms that add interesting shapes, colors, and textures to the garden. Alliums naturalize, so they're perfect for planting in large, sweeping drifts or clustering in mixed beds, borders, and containers. Mixed with muscari and anemones, allium is a good choice for a layered lasagna planting.

Cold hardy to Zone 4, easy to grow and maintain, Azureum Blue Globe ornamental onions grow best in a sunny to partially shady spot with freely draining soil having a slightly acidic pH. Allium bulbs do not like wet areas and may rot in soggy soils. Plant Azureum Blue Globe allium bulbs 6 to 12 inches apart and 4 to 6 inches deep and water well to settle bulbs. When growth starts to appear, feed bulbs with a well-balanced fertilizer. If flower production decreases over the years, dig, divide, and replant the bulbs. Ornamental onions are deer and rodent resistant.
