Allium giganteum as described by Caroline Garland, garden designer

by caroline / Tuesday, 30 July 2013 / Published in Caroline's favourite flowers

Allium giganteum or the giant onion

It’s family name: Alliaceae

 

This is one of my absolute favourites.  In fact my gardeners call it my signature plant.. but then I seem to have lots of those!
It likes full sun so a south-facing border suits it best, but it will survive perfectly well in north, west and east-facing borders provided there is some shelter from wind.  It will grow in most soils, but add a bit of grit when grown in a clay soil to help drainage. 

 

Allium are bulbous herbaceous perennials with a strong onion or garlic scent, linear, strap-shaped or cylindrical basal leaves and star-shaped or bell-shaped flowers in an umbel on a leafless stem.

Allium giganteum is a perennial with spreading, glossy, strap-shaped basal leaves which die down before the flowers. Dense globose umbels of bright purple flowers are borne .  It is reasonably hardy and has purple summer flowers but is green in the spring.  By about late July it has died back.  It reaches a height of 1 – 1.5 metres and is fabulous in the early weeks of a herbaceous border and mixes well with plants its own height or those much smaller.  It looks particularly good in a cottage or informal garden style.
