Allium 'White Giant'
A true titan of the garden, 'White Giant' brings a breathtaking combination of colossal size and pristine colour. It produces enormous, 8-inch flower heads packed with thousands of tiny, star-shaped, snow-white florets, each with a tiny green eye at its centre. Standing tall and proud on thick, sturdy stems that can reach over 4 feet, these luminous globes act like beacons in the late spring garden, glowing in the evening light. 'White Giant' is perfect for creating a sophisticated and dramatic focal point, or for weaving through deep purple alliums to create a stunning, high-contrast display of light and shadow.
