A really unusual ornamental onion with an umbrella of hanging bell-shaped creamy green flowers flushed with lilac on stiff stems in May and June. This tall exotic-looking bulbous perennial will add vertical interest in a sunny well-drained border and thrives in partial shade too. As the flowers fade they turn upright to form curious shuttlecock-like seedheads that extend the season of interest and add a twist to flower arrangements.

  • Garden care: Lift and divide congested colonies in autumn.
