Allium White Giant

Allium ‘White Giant’ is an impressive and elegant ornamental onion that brings height, light and structure to the late spring garden. Each strong, upright stem carries a large, perfectly rounded flower head made up of hundreds of small, star-shaped white blooms. The effect is clean, bright and eye-catching, particularly when planted in groups.

As one of the tallest white alliums available, ‘White Giant’ is ideal for adding vertical interest to borders and larger planting schemes. It combines beautifully with pastel-toned tulips, ornamental grasses and early summer perennials, where its fresh white colour helps lift and balance surrounding planting. Easy to grow and highly reliable, this allium returns year after year with minimal care and is very attractive to bees and butterflies. The long-lasting blooms are also excellent for cutting.
