Allium Cristophii is one of the most spectacular ornamental alliums, producing enormous spherical flower heads made up of hundreds of shimmering star-shaped lilac-violet flowers. Flowering from May to June, each impressive bloom can reach up to 20cm across, creating a dramatic architectural feature that stands proudly above borders and perennial planting. Its striking appearance makes it a favourite for contemporary, cottage and wildlife-friendly gardens alike.

Highly attractive to bees and other pollinating insects, Allium Cristophii provides valuable nectar while adding bold structure and long-lasting seasonal interest. The large flower heads are equally impressive as cut flowers or left to dry naturally, where they continue to provide texture and beauty long after the blooms have faded.

Aftercare
Allow the foliage to die back naturally after flowering so the bulbs can store energy for the following season. Leave the striking seed heads in place to provide architectural interest well into summer, or cut them for dried flower arrangements. Once established, the bulbs prefer to remain undisturbed and will reward you with spectacular displays year after year.
