  • Soil: fertile, well-drained soil
  • Rate of growth: average
  • Flowering period: June to July
  • Hardiness: fully hardy

    Dense globes of small, star-shaped, lilac-pink flowers top towering stems in summer above pale green leaves, which will start to die back before the flowers open. This gorgeous ornamental onion - the tallest currently available - is perfect for providing vertical interest in a sunny border. Try it dotted in small groups among ornamental grasses, or as part of a Mediterranean scheme

  • Garden care: Split and divide large clumps in autumn or spring.
