Allium 'Mount Everest'
An iconic and utterly reliable white allium, 'Mount Everest' brings pure, classic elegance to the garden border. It forms large, 6-inch globes of clean, crisp white flowers on strong stems that reach a stately 3-4 feet. The flowers have a beautiful, dense structure that holds up well in spring weather and lasts for weeks. 'Mount Everest' is incredibly versatile; it looks stunning planted in formal blocks, woven through a cottage garden planting, or used as a cool, calming counterpoint to brighter colours. As the flowers fade, the seed heads turn a lovely shade of tan and provide excellent winter interest.
