A colleague of mine is trying to identify a flower that was seen in County Donegal in August. Her father, a keen wildflower enthusiast, has tried every book he has to identify it but has had no luck. It is possible it has grown from seed from a cultivated plant in someone's garden.

Can anyone shed any clues? One of the photos shows the flower head and leaves, the other a closer view of the flowers.

Many thanks,

Jane
