Allium flower
Introduction
The photograph on this page of Allium flower by Bob Harvey as part of the Geograph project.
The Geograph project started in 2005 with the aim of publishing, organising and preserving representative images for every square kilometre of Great Britain, Ireland and the Isle of Man.
There are currently over 7.5m images from over 14,400 individuals and you can help contribute to the project by visiting https://www.geograph.org.uk

After assistance from other geographists in the forum, I am going to suggest this is Allium christophii or Allium giganteum. It is in the garden at Chancellor's hotel.
