Product Description

Allium Mount Everest produces enormous pure white domes 15cm across formed from compact clusters of small spiky star shaped flowers. These will look stunning soaring up at the back of the border and as you can see from the illustration are a natural partner to the stunning Allium Mars (purple). As with other alliums, its attractive curled green leaves will wither before the flowers appear in early summer so we recommend accompanying them with low-growing plants to provide filling foliage over the base areas. Height 1.2m. Flowering May-June. 18cm+ bulbs supplied.

Growing at a glance…

Plant in fertile, well-drained soil at approx 10cm apart and at a depth of roughly 3-4 times the size of the bulb. Larger bulbs should be spaced 20cm apart. Leave untouched for a number of years until the bulbs have multiplied and divide if necessary. Smaller alliums can be grown in containers, but ensure it's large enough to space the bulbs an appropriate distance apart.
