Allium 'White Giant'

Plant details

Allium 'White Giant' bears beautiful, large globes of bright white flowers, in early summer. It's perfect for growing in drifts or large clumps in a sunny border, or large container, and makes an impressive cut flower. Like all alliums, its flowers are attractive to pollinators, including bees.

For best results, grow Allium 'White Giant' in fertile, well-drained soil in full sun. Plant bulbs up to three times their diameter, in autumn. It's not fully hardy and in colder regions should be mulched, or planted in pots and moved to a frost free area in autumn.
