Is there anyone who can put a name to this Allium please?
I've grown this for ages and it does really well in the garden, multiplying steadily into a clump without ever seeding or spreading around elsewhere. It's a nice little thing and I've now got it established in various places.
To be honest, beyond the usual suspects that are commonly encountered, I don't know much about Allium. Any ID suggestions would be most gratefully received!
Thanks, Ben
