Dear Mark, Many thanks for the most helpful and erudte information. It was in mid October last year that I was in the Peloponese. I did find two other species, lots of Allium callimischon and something much like Allium chamaespathum as well. The one I would like to identify if possible was pale yellow not green nor white. I don't have a photo of it sorry, as it is not performing for me this year.It has just leaves. I will take photos if it flowers next year. Kind regards, Mark M.W.
