Allium 'Mount Everest' is an impressive large-flowered white ornamental onion that has been highly appreciated in both ornamental gardens and professional cut flower cultivation since its introduction in 1993. This cultivar was developed by A. Langedijk & Co. and is known for its vigorous growth, elegant appearance, and large, spherical flowers. Thanks to its stately flower stalks and pure white flower color, Allium 'Mount Everest' is one of the most popular white alliums for borders and flower arrangements.

The plant reaches a height of approximately 100 to 125 centimeters and forms sturdy, upright flower stalks on which the large, round flower heads proudly stand out above the surrounding vegetation. Flowering occurs in June. The spherical inflorescences consist of hundreds of small, star-shaped white flowers that together create a tightly formed sphere. The fresh white color provides a stylish and airy effect in the garden and combines beautifully with perennials, ornamental grasses, and dark-flowering varieties.

Allium 'Mount Everest' is particularly popular as a cut flower. The long, sturdy stems and striking flower shape make this cultivar highly favored by cut flower growers, who frequently supply the flowers to the flower auction. The flowers also retain their decorative value for a long time in bouquets. Even after flowering, the drying flower heads remain attractive and provide structure in the border.

This ornamental onion grows best in a sunny location but also tolerates light partial shade. The bulbs are planted about 15 centimeters deep with a spacing of approximately 25 centimeters between them. For a beautiful, full result, an average of twenty bulbs per square meter is recommended. The plant is not fragrant but attracts plenty of bees and butterflies, thereby contributing to a lively garden.

In addition, Allium 'Mount Everest' is highly resistant to deer and rodents. With its impressive height, strong flower stalks, and stunning white flowers, this ornamental onion is an elegant and timeless eye-catcher in any garden or flower border.
