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!

Care and cultivation advice
Plant the bulb with the pointed end facing upwards. Plant it at a depth that is 2-3 times the height of the bulb. If there is often a risk of frost in your area, you can plant it even deeper to provide better protection for the bulb. Don't forget to water after planting.
For prolonged and recurring blooming, allium bulbs need to be fertilized in the upcoming seasons, especially if the soil is poor. This should be done when the bulb is actively growing during spring and early autumn. Spread composted manure that is rich in phosphorus and potassium or use classic onion fertilizer.
