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