This truly beautiful blue color is from the Allium Caeruleum, it likes to be in full sun or in a place with partial shade. It is a fantastic cut flower, but not suitable for a pot. It is a delicious ornamental bulbous plant of the onion variety. This sky-blue ornamental onion originally comes from the steppe region and the salty marshes of Eastern Europe and Western Asia.

Many ornamental onions get ugly yellow leaves in their flowering time, but the Caeruleum is not bothered by this. The leaves largely disappear during growth so that it is less noticeable. This blue topper won an award in 1993 called The Award of Garden Merit. The most striking thing about this allium is its magical sky blue color.

  • For the distance between the bulbs, make sure it is 2 times the diameter of the bulbs.
  • Plant the flower bulbs in the hole with the pointed side facing up or with the root base facing down.
  • Cover the allium bulbs with soil and water them well.
