Mystery

No idea what this pretty little flower is - it crept out from under another plant a couple of days ago. Must have self-seeded from somewhere or other.

To Jacqui's this morning, to cut her front lawn. It's not very big so it doesn't take long, but it's at a 45° angle, so it's quite strenuous and hot work in this weather! After that a well-deserved coffee in her sunny back garden.

PS. Thanks to Google, mystery solved. It's blue flax.
