Product Information

Allium ‘Mount Everest’ is a fabulously statuesque variety with huge flowerheads that look like exploding white fireworks. Made up of around fifty individual star shaped flowers, they form stunning globes up to 15 cm (6 in) in diameter.

Easily growing to 1.2 m (4 ft) tall, the robust, straight flower stems rise up high about the broad, strap-like green foliage, and look stunning as the sway amongst other plants. Recommended by the RHS as a 'Plant for Pollinators' the flowers are produced throughout May and June and are a favourite with butterflies, bees and other pollinating insects.

As the flowerheads gradually turn to seed, they maintain their shape and will look amazing left on the plant over the winter, especially on frosty days. They’re also magificent as cut flowers with there huge size creating bold, extravagant arrangements, whether still in bloom or as dried seed heads – which can last for years.

Fully deserving its coveted RHS Award of Garden Merit, you can be sure that this is a proven garden performer, guaranteed to be suitable for UK gardeners at every level of experience. You can therefore plant this in the garden with confidence, for stunning displays for many years to come.

Preferring a sunny location, alliums are not too fussy about soil type and will grow well, naturalising and multiplying over the years. Clumps can be dug up and split every few years to stop them becoming congested.

Supplied as 3 bulbs, size 18/20, ready to plant in autumn, growing to a height of 1.2 m (4 ft) and width of 30 cm (1 ft).

Underplant with hostas, ferns or other low-growing, hardy perennial plants which will help to disguise the leaves as they fade.

Care Information

Planting Advice for Alliums

  • Find a location where the soil drains well and where they will receive full sun.
  • Plant allium bulbs in early to mid-autumn in a sheltered site to prevent the top-heavy flower spikes from getting blown over.
  • Dig over the soil and remove any weeds before planting.
  • Water well after planting, saturating the soil around the bulbs. Once established, alliums are drought tolerant.
  • In borders, plant bulbs in early autumn at a depth of about four times the diameter of the bulbs.
  • In containers, alliums will do well in deep pots with a good general-purpose potting compost with a handful of horticultural grit added. 

Aftercare Advice

  • After planting, feed with a general-purpose feed such as our Blooming Fast Superior Soluble Fertiliser.
  • Dried flower heads can be removed and made into indoor decorations or left on the plants to self-seed.
  • Divide alliums every three to four years or when the plants begin to look overcrowded and blooming decreases.
  • Lift the bulbs with a garden fork or spade and pull the bulbs apart.
  • Replant some in the original location and plant the remainder in a new location. 

Pruning and trimming advice

  • The leaves die down at flowering time, so it’s best to plant alliums where this foliage is masked by that of other plants.
  • Avoid removing them while still green, as they provide the bulbs with energy for the following season.
