Elevate Your Garden with Allium Mount Everest

Allium Mount Everest is a striking ornamental onion, prized for its globe-shaped heads of pure white, starry flowers. Each sturdy stem supports a sparkling sphere of over 50 blooms, rising above lush foliage to create an eye-catching focal point in any garden.

• Variety: Mount Everest – renowned for tall stems and pristine white flowers
• Mature Size: Height 90–120cm (35–47in); spread 15cm (6in)
• Flowering Period: Late spring to early summer (May–June)
• Lifespan: Hardy perennial; bulbs return every year once established

Why Grow Allium Mount Everest?

• Dramatic Vertical Accent: Tall, upright stems add structure and movement to borders and mixed beds.
• Seasonal Bridge: Blooms when many spring flowers have faded, keeping your garden vibrant into summer.
• Elegant Pairings: Plant alongside purple alliums like 'Globemaster' or ornamental grasses for a contemporary look.
• Pest Resistant: Alliums are naturally unappealing to deer and rabbits.

Planting & Care Guide
