Allium 'White Giant'

Allium 'White Giant' is a magnificent and majestic ornamental onion that combines height, elegance, and brightness in one impressive plant. It blooms in May/June with large, perfectly spherical flower heads in pure, chalk-white, made up of countless small star-shaped flowers that together form a dense and harmonious globe.

The blooms are held on tall, sturdy stems that can reach up to 120–150 cm, rising proudly above broad, blue-green foliage that dies back as flowering takes over. Allium 'White Giant' is ideal as a structural element in large perennial borders, adding height, rhythm, and an almost sculptural purity. A luminous and elegant classic that brings a sense of calm and refinement to the early summer garden.
