Allium oleraceum. This one I spotted in Pornainen, Southern Finland.
This individual had studied the Flora because the site fitted the description well.
A dry 'meadow' surrounding a small flat rock. Just maybe 20-30 individuals
each summer. I was 1st introduced to this species on an exciting study excursion in Helsinki
by prof. Hintikka in 1991 - ever since I've had my eyes open for Allium's!
