Flower Friday....Daisy?

It was a beautiful sunny morning, and so warm when I walked back from the supermarket with my prize of two trays of violas...yes, they had plenty there still, I was so pleased.
Around 1.30pm it suddenly clouded over, the temperature dropped, it's windy again, it looks like rain and is now a lot colder! Think the heating might be going on later!
I believe I have identified these little daisy like flowers with ferny leaves as chamomile, but I have no idea how they arrived in the plant pot....thanks to Bikerbear for hosting:)

Thanks for the lovely comments and stars yesterday x
