Allium Mount Everest is an elegant ornamental allium producing large, perfectly rounded flower heads made up of hundreds of pure white star-shaped florets. Flowering during May and June, these striking blooms are carried on tall, sturdy stems reaching approximately 120cm in height, creating dramatic vertical interest while attracting bees, butterflies and other beneficial pollinators. Its crisp white flowers provide a beautiful contrast against colourful perennials and ornamental grasses, making it a standout feature in any planting scheme.

Perfect for perennial borders, cottage gardens, gravel gardens and contemporary landscapes, Allium Mount Everest combines beautifully with roses, peonies and late spring flowering plants. The long-lasting blooms are excellent for cutting, while the attractive seed heads continue to add architectural interest well into summer.
