May I suggest you have a look at this link for a UK company that sells Alliums.
It shows excellent pics to illustrate many of the ornamental onions...Alliums that you will find growing in London UK.
Including the 2 mentioned in this thread....Allium sphaerocephalon and Allium Cristophii
In yet another thread you show the Allium seed heads.
