    The grey-green leaves of this ornamental onion generally have started to die back when the flowers emerge in early summer. These sit on tall, sturdy stems forming flattish clusters that create a striking silhouette. Each creamy-white to pale lavender flower has a pronounced ovary at its heart, which looks a little like a green pearl, nestled in the centre. Very pretty - and in big demand after its appearance in Cleve West’s garden at Chelsea in 2012.

  • Garden care: Plant bulbs 15cm deep and 15cm apart to enjoy the full effect of the flowers. Avoid excessive moisture from late summer when they become dormant. Over-large clumps can be lifted and divided in autumn or spring.
  • CAUTION do not eat ornamental bulbs
