Allium Mount Everest Flower Bulbs produce large pure white globe-shaped flower heads up to 12cm (5in) across on sturdy stems reaching around 120cm (47in). Their height and clean colouring make them an excellent structural plant for mixed borders and naturalistic schemes.

Supplied as a pack of 3 bulbs, this RHS Award of Garden Merit variety flowers from May to June. The nectar-rich blooms attract pollinators, while the architectural seed heads remain decorative after flowering.

Plant from September to November in free-draining soil in full sun or partial shade.

Bulb size: 18/20
Bulb sizes are measured by circumference in centimetres. An 18/20 bulb measures approximately 18-20cm around. Larger bulbs generally contain more stored energy, helping to support strong growth and an impressive flowering display.
