Overview

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.

Care guide

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.
