Allium 'Gladiator'

Allium 'Gladiator' is one of the most powerful and iconic ornamental onions—a true giant in the early summer bloom. Flowering in May–June, it produces large, globe-shaped flower heads in a vibrant violet hue with a subtle metallic sheen. Each globe, up to 15 cm in diameter, is made up of tightly packed, star-shaped flowers that together form a perfect architectural sphere.

The sturdy stems can reach up to 120 cm in height, holding the blooms high above the broad, blue-green foliage, which gradually dies back during flowering. 'Gladiator' serves as a structural focal point in perennial borders, combining strength and elegance in one striking display. A reliable and long-lasting variety that brings both presence and color to the garden year after year.
