This is the largest allium grown in the UK which also makes it the biggest of the allium bulbs for sale on this site. Allium giganteum lives up to its name; the violet/mauve flowerhead is as large as a small melon and sits atop a strong stem of up to 130-150 cms tall. The long strappy leaves are all at the base of the stem and will have mostly died back when the flowers open. The seed head that follows changes in colour through pink to a light brown - almost straw - colour. The heads dry very well and are ideal for dried flower arrangements. This is an imposing allium, but not as showy as Purple Sensation or Purple Rain (ideal for Prince fans).
Allium giganteum hails from mountainous Central Asia where it enjoys the excellent drainage found in the foothills and lower mountain slopes. This explains its need for sun and excellent drainage in the garden. In the garden, it is a plant that prefers a well drained and sunny situation.
