The Allium 'White Giant' as the name might suggest, is a massive allium with beautiful pristine white flowers. This enormous allium can reach a staggering 150cm with flower heads as wide as 15cm in diameter. The White Giant is best planted in autumn from September to December time. The Alium then blooms in early spring through to summer.
The Allium 'White Giant' does best when planted about 10cm deep in well-drained, nutrient-rich soil in a sunny area of the garden. Taller alliums like this one can also benefit from shelter on one side to help prevent the tall flower spikes from being blown over.
Planting Time: September - October
