You can tell by the size of the bulb these are going to be truly magnificent in your garden next summer! This giant of the Allium world is the largest flowering variety on sale in the UK growing on the tallest stem 1 - 1.5 meters when at full maturity. The flower head achieves a width upwards of 15 cm so its best to leave plenty of space between them when planting.

I see these on sale every year in the garden centre ready to flower for £15 each and kick myself for not buying the bulbs in the Autumn! Why pay that for just one when you can have a swathe of your own for the same cost with the added satisfaction you grew them?

Dense lilac-pink flowering heads made up of hundreds of individual flower buds which burst open from June to July. Plant directly into your beds and borders or they will be perfectly happy in pots and containers** on the patio with a rich humus material such as our Clover - Peat based or Heart of Eden - Peat Free multi purpose composts.

Alliums offers a three to four weeks display before the petals fall making way for decorative seed heads lasting the rest of the year. Excellent as a cut flower or left in the garden offering fantastic structural interest in the garden for months after! These can be left to dry out completely giving you masses of seed to try growing your own, which will take a few years!

Supplied as 18/20 cm (circumference) bulbs ready to be planted our straight away to ensure they have a good head start before winter takes hold. Strong root development is the key to performance of next year's flowers, early planting will ensure your beds and borders are the talk of the street making your neighbours green or pink with envy!

How to grow me

The allium is happy to grow in most soil types but will prefer a well drained spot* in full sun. They should be planted 15 cm deep for longevity and stability, with spacing between bulbs a at 20 cm space to avoid overcrowding and the flower heads touching. Planting in groups of odd numbers helps to showcase the elegance and individuality of these Chelsea Flower Show favourite. These should be planted in sheltered spots due to the height they achieve, windy outlooks are not suited to this variety although if they are planted deep enough some support can be used and at these prices its worth giving them a go if you are unsure?!

*Drainage in the form of horticultural potting grit can be added to the soil directly under your bulbs to ensure the roots do not sit in water and rot away. Clay soil that retains water may need improvement for successful flowering.

**Bulbs grown in pots are more susceptible to frost damage and should be protected during extreme weather events to prevent failure.
