Allium flower colour change

This question was asked by
B. Dwyer

I have a blue flowering allium – variety unknown. This year it has only 2 flowers, both of which are white! Could this be stress induced given the extreme weather we\’ve had this year?

Hi Barbara

Yes stress from the heat can cause flowers to revert to white. Isn’t nature wonderful.

My alliums were spectacular! When you say ‘cut back’ – do you mean take the heads off when finished or cut back the stalks as well?. The dead heads look very attractive but I will cut them off if it’s best. The flower heads when in full bloom had a unpleasant scent when up close – is this natural?

HI Thelma

Yes Alliums are part of the onion family and will smell similar to an onion unfortunately.

Once the whole allium head and stem turns yellow/brown and hollow, it can be removed completely.

We bought som alliums and Fritillaria Imperialis bulbs from you at Hampton Court harden show.

Should these be planted now? In the Autumn? Or either?

Thank you.

HI Karin

Your alliums a fritillaria both need planting in the autumn so store them somewhere cool and dry before then.

Allium bulb names

This question was asked by
Barbara E – 

HI, I bought a number of allium bulbs at your stall in malvern and had a chat about growing, with some great advice thank you. Now, I have no idea what species they are !! I know one is allium schubertii, but no idea of the rest. I think I bought some of all your offerings. 4 types large bulbs and 10 small bulbs. Would you be kind enough to let me know which ones you were selling please. I can then Google to see what I can look forward to next spring. Thank you. Hope you had a good show – we certainly enjoyed it.

Allium Gladiator

This question was asked by

In 2019 I put down a large number of allium Gladiator, they bloomed in 2020 but nothing at all this year. Also have two large pots in which I had a mix of smaller allium and almost all have disappeared, I wonder why please?

Hi Jerry

It could be a number of factors…How did you care for them after the alliums had finished flowering? Did you remove the flower heads and leave the stems and foliage to die back to feed the bulb so it flowers the following year? Have you checked to see if the bulbs are still there and intact? Do you have drainage holes in your pots – they may have got too wet and rotted away.

Alliums for planting in Portugale

This question was asked by

Should I be planting Alliums in Autumn in Portugal or at another time.Also will they tolerate full sun.

Hi Peter

Our Alliums are available to plant in September through to November. They will be fine to plant them then in Portugal as long as you have a cold dormant phase. They will just flower earlier due to your warmer temperatures.

Deadheading my alliums

This question was asked by
Merilyn Ainley

Most of my large purple alliums and some white ones have finished flowering. Do I cut the tops off and if so how far down to I prune them.
Looking forward to my bulbs I have just ordered from you.


We advise leaving at least 50% of the stem and allow to to fully die back before removing it entirely.
