Allium sp. Lisbane, County Down, Northern Ireland.
A week ago I asked for help identifying some flowers. (http://www.imb.biz/page.php?pg=diary&d=2007-06-27) I got some helpful replies, and I’ve got some basic identification. Thank you to all those who responded.
As a result I’m confident enough to post this image and to tell you that it is an Allium.
