This is mapped to Bicester. Is that correct?
(I was wondering if this was the coastal subsp. gummifer.)
I'm not sure why it's done that but I typed in West Wittering Beach. I do have some with a purple floret in the middle from some wild flower seed in my Back garden (in Bicester) and also saw it on the beach and wondered what it was.
