Allium

Allium cristophii

• Position: full sun
• Soil: fertile, well-drained soil
• Rate of growth: average
• Flowering period: June to July
• Hardiness: fully hardy
  
  Huge globes ofsmall, 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.
