The pure white, perfectly globular flower heads of Mount Everest appear at a time when most spring bloomers are fading, extending the season with fresh, airy texture perfect for cutting and arrangements. Its height and architectural form provide striking vertical interest in beds, while its ability to attract pollinators makes it as useful to local bees and butterflies as it is beautiful to human eyes. As a perennial that returns year after year in cold climates, it's a no-replant wonder.
Mount Everest Allium shines as a cut flower, where its sturdy stems and long-lasting globe blooms carry exceptional vase life. It's recommended for landscape beds where its upright form and pale spherical flower clusters create focal points and architectural interest. The flowers attract pollinators throughout their bloom window, making it both ornamental and ecologically valuable.

Plant bulbs in fall for spring blooming. Set bulbs at a depth of approximately three times their height, spacing them 12 inches apart in prepared garden beds. Ensure soil drains well to prevent bulb rot during winter dormancy.
Cut flowers when the globe flower heads are fully formed and white petals are open but still crisp, typically in late spring to early summer. Harvest in the early morning for longest vase life, cutting stems at ground level with a sharp knife. These blooms are exceptionally long-lasting in the vase.
Deadhead spent flower heads after blooming concludes if you prefer a neat appearance, or leave them standing for late-season architectural interest and to support pollinators. Once foliage yellows in late summer, allow it to die back naturally to replenish the bulb for next season's growth.
