Allium ‘Mt. Everest’ is a striking ornamental onion known for its tall, sturdy stems topped with large, pure white globe-shaped flower heads. Blooming in late spring to early summer, each 4- to 6-inch bloom rises 3 to 4 feet high and adds a clean, architectural element to perennial borders, formal plantings, and cut flower gardens. This hybrid is deer and rabbit resistant, thrives in full sun and well-drained soil, and adds a bold contrast when paired with darker or more colorful flowers.

Why choose ‘Mt. Everest’ Allium:

• Bold vertical accent: Tall stems and white flower globes make a dramatic garden statement

• Late spring interest: Blooms after spring bulbs and before summer perennials peak

• Easy to grow: Drought-tolerant, pest-resistant, and low maintenance

Cultivating tips:

• Sun exposure: Requires full sun for best flower size and stem strength

• Soil needs: Prefers well-drained soils; avoid wet locations or heavy clay

• Maintenance: Allow foliage to fade naturally; divide bulbs every few years

Designs for your garden:

• Formal borders: Adds clean lines and contrast in structured garden designs

• Pollinator gardens: Nectar-rich blooms attract bees and butterflies

• Cut flower beds: Long-lasting and eye-catching in floral arrangements

Ecological considerations:

• Non-native hybrid: Offers some pollinator support but limited ecological function

• Pollinator appeal: Blooms provide mid-season nectar

• Well-contained: Does not spread aggressively or reseed
