This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: full sun
  • Soil: fertile, well-drained soil
  • Rate of growth: average
  • Flowering period: June
  • Hardiness: fully hardy
  • Bulb size: 12/14


  • Tightly packed spherical umbels of 50 or more white, star-shaped flowers appear on upright, ribbed stems in early summer, above the strap-shaped foliage, which starts to die back before the flowers emerge. 'Mount Everest' is a tall allium with an outstanding architectural form that is ideally suited to gravel gardens.

  • Garden care: Bulbs can be planted 15cm deep and 15cm apart. Pot-grown plants can be enjoyed as they are while in bloom, but as the flowers fade, they should either be potted up or planted out in the garden. Avoid excessive mositure when the plants become dormant (from late summer) and lift and divide over-large clumps in autumn or spring.
  • Pets: TOXIC if eaten; Humans: Ornamental bulbs - not to be eaten
