Allium Caeruleum, also known as Azure onion, has received its name thanks to its unique clear blue color. Caeruleum is a delightful allium variety that forms enchanting flower globes composed of sweet little flowers in a lovely blue shade that closely resembles the cornflower. It is lovely to use as a cut flower and to incorporate into bouquets, thanks to its exceptional color and magical shape. Deer and hares do not like allium, which means you can have your fantastic spring bulb all to yourself!
