Allium Collection Ornamental Onion Bulbs

Plant Allium Collection ornamental onion bulbs in the fall before the first frost, and by summer, enjoy a stunning blend of clustered white, yellow, and rosy-red flowers. These summer bloomers range in height from 6 to 15 inches, creating a picture-perfect display. This collection includes Allium Neapolitanum (white garlic), Allium moly (golden garlic), and Allium ostrowskianum (pink lily leek [syn. A. oreophilum]). Pollinators, including bees and butterflies, are drawn to these fragrant flowers, which also make lovely posies and vibrant summer bouquets.

These bulbous perennials have an upright habit and naturalize quickly, multiplying and spreading to create an even more spectacular display year after year, without becoming overly aggressive. While related to garlic, onions, chives, and shallots, ornamental alliums stand out with their beautiful blooms that add unique shapes, colors, and textures to garden beds, borders, and patio pots.

Allium Collection varieties are easy to grow and require minimal care, making them a carefree addition to your garden. Plant the bulbs 4 to 5 inches apart and 5 inches deep, then water them well. Once growth begins to appear, feed the bulbs with Espoma Organic® Bulb-tone® Bulb and Flower Food. Choose a sunny location with well-draining soil and a slightly acidic pH for best results. If the plants become overcrowded over time and flower production decreases, simply dig up the bulbs, divide them, and replant to rejuvenate the display. The ornamental onions in this blend are also deer and rodent resistant, ensuring a beautiful and undisturbed garden.
