For many years already the garden world enjoys her good looking daughter Allium Ambassador. But I’m glad there still is a flower and bulb growers who adores mother even more and re-introduced her again.

Allium giganteum has fallen into oblivion for a bit and that was a pity because her beauty is beyond compare and she is the latest and longest blooming of all the large flowering Alliums. She mainly owes her come-back to the flower trade because flower arrangers love to use this ornamental onion in their flower arrangements.

When the summer starts Allium giganteum always is in full bloom and despite the warm weather she amazes us with her long blooming period. Over and over again fresh flowers appear from the inside of flower ball and she blooms longer and longer and her size grows larger and larger.

Planting and caring for Allium bulbs

Plant allium bulbs in a sunny to lightly shaded spot in well-drained soil. It is best to plant the bulbs in clusters to create a natural and colourful effect. Alliums look lovely amongst perennials, extend the flowering season of spring bulbs and often return year after year.

Read our comprehensive guide on when and how to plant and care for allium bulbs.

You can order allium bulbs from us from early spring onwards for the next planting season. We take care of the proper storage and only ship the bulbs when the autumn planting season begins. This means you receive fresh bulbs at the right time for planting and a strong start in the garden.

Allium bulbs are planted in autumn. Many Allium varieties can then remain in the same place in the garden for many years.

The correct planting depth depends on the variety. For many larger Alliums, we recommend a planting depth of around 10–15 cm, while smaller varieties may be planted less deeply.

For the best effect, we recommend planting Alliums in groups of five or more bulbs. This allows the flowers to make a stronger display in borders or natural-style plantings.

Many Allium bulbs can remain in the same place for many years. If the bulbs become too crowded over time, they can be divided in autumn and replanted.

Yes. Alliums are among the flower bulbs that are particularly attractive to bees. On our website, especially bee-friendly bulbs can also be recognised by the RHS logo.
