Allium stipitatum Mount Everest

Allium Mount Everest – as the name suggests is a tall and white allium. The stem reaches up to 120cm with a perfect spherical globe on top. Hundreds of star-shaped white flowers will last for weeks. As they mature the head becomes increasingly green as the seed heads start to swell. As with all alliums, the heads are packed with flowers so there is ample food for bees and butterflies.

The foliage is long, broad and waxy. It can be very domineering over your garden bed, so be sure to give them plenty of space. The leaves may spread 40cm wide to 40 cm high and starts to die off once the flower appears.

Allium Mount Everest bulbs flower in May and June. This is when most of the spring bulbs have flowered and finished and summer flowers haven’t quite hit their stride. Because of their long stems they reach over the green foliage of shrubs and newly growing perennials as beacons of colour. They look fantastic in a busy garden.

How to plant

Alliums like lots of light. Plenty of water but they don’t like to be drenched. Make sure they have free draining soil. Dig a hole between 15 and 20cm deep for large allium bulbs. Plant them at least 20cm apart.

They can be planted in autumn between September and December.

Alliums are hardy bulbs and can be left in the ground. They often split into many smaller bulbs. It is worth digging them up in autumn to divide them and give them more space which will help them later on.

Try planting them with Gladiator for contrast.
