Giant Allium Flower Bulbs

Giant alliums, such as Allium 'Globemaster,' make a striking statement with their massive, softball-sized flower heads perched atop sturdy stems reaching 3 to 5 feet tall. Blooming in late spring to early summer, they bridge the seasonal gap between spring bulbs and summer perennials, adding architectural height and bold color to borders and mixed plantings.

Their dense clusters of star-shaped florets form perfect spheres in shades of purple, lavender, and white, attracting bees, butterflies, and admiration alike. Low-maintenance and deer-resistant, these dramatic blooms offer effortless beauty year after year.

Key Differences Among Giant Purple Alliums:

• Allium 'Ambassador' – The tallest, reaching four feet, with six- to eight-inch violet-purple globes that last exceptionally long.
• Allium 'Gladiator' – Slightly shorter at three to four feet, featuring six-inch reddish-purple globes densely packed with star-shaped florets.
• Allium 'Giganteum' – Grows three to five feet, producing six-inch lavender-purple flower heads with a more open structure.
• Allium 'Globemaster' – More compact at 28 to 36 inches, but with the largest flower heads at eight to ten inches across, forming dense, rounded clusters.
• Allium 'Pinball Wizard' – Stands at 24 to 30 inches, with six-inch silvery-lavender globes that are tightly packed for a bold visual impact.
