Allium stipitatum 'Mount Everest'
ornamental onion or allium bulb
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.
How to care for Allium stipitatum Mount Everest:
Allium bulbs are easy to grow in a sunny spot with freely drained soil, or a good quality potting compost. Ideally they should be planted in September or October, but could also be planted in early November in milder regions. Dig holes roughly three times as deep as the diameter of the bulb and place them at the base, pointy side up before gently infilling and watering to settle them in. In early spring, as growth begins, apply a balanced, slow-release fertiliser, and allow the plants to die back naturally and completely before tidying away.
