Allium 'Christophii'

Plant details

Ornamental onions are grown for their globe shaped flower heads that remain attractive once dried as well in flower. Allium christophii produces striking globes of violet, star-shaped flowers in early summer. The long, linear leaves die back before the blooms appear in early summer.

Allium christophii is a fantastic choice for sunny borders, and works well when planted in drifts with ornamental grasses and other alliums. It makes a wonderful cut flower.

For best results, plant bulbs in fertile, well-drained soil up to three times their diameter. Grow in well-drained soil in full sun. 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.
