Allium stipitatum ‘White Giant’ Bulb

Allium stipitatum ‘White Giant’ is an impressive ornamental onion cultivar renowned for its large, globe-shaped flower heads composed of numerous star-shaped florets in pure white. Blooming in late spring to early summer, these striking umbels are displayed atop tall, strong stems rising above broad, strap-like leaves. This variety thrives in full sun and prefers well-drained soil, making it well-suited to borders, rock gardens, and mixed perennial plantings where it provides bold architectural interest and a bright floral focal point. ‘White Giant’ is drought-tolerant and low-maintenance once established, attracting pollinators such as bees and butterflies, which supports garden biodiversity. Its dramatic size, brilliant white colour, and elegant form make it a popular choice for gardeners seeking a standout summer-flowering allium with long-lasting impact.
