Home | Plants | Bulbs | Allium caeruleum (aka A. azureum) Blue-flowered Ornamental Onion

Allium caeruleum (aka A. azureum) Blue-flowered Ornamental Onion

Inch-and-a-half globes of gorgeous true-blue flowers are borne abundantly atop 12”-18” stems in May and June.  Native to Siberia, this easy-to-grow flowering onion is very accommodating, and will grow in sun or part-shade almost anywhere, including xeriscape gardens and at high elevations. Dry seed-heads are also attractive in the garden and in dry bouquets, but this flower re-seeds readily, so if you want to maintain population control we recommend dead-heading.

Looks great planted with Aquilegia chrysantha (Denver Gold Columbine), Pineleaf Penstemon, or Malva moschuta ‘Alba’.

Plant 3″ deep, 2″-4″ apart. 12’-18” tall, Late Spring, Summer (May-June), hardy to Zone 3.
