Huge globes of small star-shaped, pinkish-purple flowers appear in summer above narrow, grey-green leaves. In bloom these fabulous globes - up to 20cm (8in) in diameter - have a metallic sheen. The faded flowerheads hold up well in the border and are useful for dried flower arrangements. Perfect for a sunny site, dotted in small groups among ornamental grasses, or as part of a Mediterranean scheme. Alliums look best planted between medium-sized herbaceous plants, which help to mask the strap-like leaves, which fade by the time the flowers appear.
How to care for Allium cristophii:
Allium bulbs are easy to grow in a sunny spot with freely drained soil, or a good quality potting compost. Ideally they should be planted in September or October, but could also be planted in early November in milder regions. While keeping the size of the flowerhead in mind and avoiding overcrowding, dig holes roughly three times as deep as the diameter of the bulb and place them at the base, pointy side up before gently infilling and watering to settle them in. In early spring, as growth begins, apply a balanced, slow-release fertiliser, and allow the plants to die back naturally and completely before tidying away.
