I think this yellow 'Wild daisy' is Ragwort. It's known as Cushag in the Isle of Man, where it is the national flower. Cushag was the name of one of our school's Houses. Disliking this flower, I was relieved not to be in Cushag, but rather Barrule, a fine hill which overlooks Ramsey.
@domenicododaro Absolutely, but I only saw him when I came to edit the shot... this is about a third of the frame. He's bright red and very striking against the yellow blooms but I haven't been able to find another like him.
