Allium Mont Everest 2 Litre Pot

Allium ‘Mount Everest’ – Tall White Flower Spheres for Striking Spring Contrast

Allium ‘Mount Everest’ is a dramatic and elegant ornamental onion, producing large, globe-shaped flower heads in crisp, pure white. Flowering in late spring, the rounded blooms sit proudly atop tall, sturdy stems, creating bold vertical accents within borders.

The luminous white spheres stand out beautifully against darker foliage and richly coloured perennials, making this variety especially effective in contemporary or monochrome planting schemes. Planted in groups, it creates a rhythmic, architectural effect that brings cohesion and height to mixed borders.

Highly attractive to bees and other pollinators, ‘Mount Everest’ combines strong visual presence with ecological value. The blooms are long-lasting and can be left to form decorative seed heads, extending interest into early summer.

Thriving in full sun and well-drained soil, this hardy allium is reliable and low maintenance. Once established, it returns year after year, providing consistent late spring structure and colour.

Clean, architectural, and wonderfully versatile, Allium ‘Mount Everest’ is ideal for gardeners seeking tall white statement flowers with dependable performance.
