Allium cristophii
- Add a touch of phenomenal, sparkling magic to your garden with the spectacular, huge, airy globes of metallic, silvery-amethyst, star-shaped flowers.
- Allium christophii, the 'Star of Persia', features incredibly delicate, open flower heads that look like breathtaking, exploding fireworks hovering above the border.
- This allium creates a brilliant, highly sophisticated 'see-through' effect, allowing you to plant it near the front of a bed without blocking the plants behind it.
- It is an absolute powerhouse for attracting wildlife, drawing in huge numbers of bees and fascinating pollinating insects throughout the early summer.
- The massive, spiky seed heads dry perfectly on the stem, offering phenomenal, long-lasting architectural structure that looks utterly spectacular when caught by the winter frost.
