Allium 'Azureum (Caeruleum)'

9cm Plant x 2


Commonly known as the Blue Globe Onion or Blue Ornamental Onion, is an ornamental allium species admired for its stunning blue-violet flower heads. Each head is composed of numerous individual star-shaped flowers. The flowers are a striking blue-violet or sky blue color, creating a vibrant and eye-catching display. The flower stalks typically reach heights of 1 to 2 feet (30 to 60 centimeters), making them a versatile choice for various garden settings. They work well in mixed perennial beds, borders, rock gardens, and naturalized areas. These alliums can also be used as cut flowers in floral arrangements.


What am I Buying?

Bulbs are a form of dormant plant which when planted in the correct conditions produce a full plant over time. Plants which naturally survive as bulbs will usually die down into the ground when their season is finished in order to store their energy to return the following year.

Bulbs are a form of dormant plant which when planted in the correct conditions produce a full plant over time. Plants which naturally survive as bulbs will usually die down into the ground when their season is finished in order to store their energy to return the following year.

Planting Bulbs

Most bulbs should be planted at a depth 2-3 times their own depth. e.g. a 5cm bulb will be planted at 10-15cm deep.

Plant bulbs with their shoot side facing upwards up. If unsure which side, it's best to plant the bulb "laying down".

Cover with soil and lightly water in. Avoid the ground staying overly wet as it may cause the bulbs to rot.

Feed weekly with a high potassium feed, such as tomato feed, once shoots appear.

Stop feeding when the foliage begins to die back. Allow the foliage to die back naturally as this will support growth in future years.
