This is the distinctive flower of Love-in-a-Mist, captured with black card behind, then darkened a little in PS. All those in my garden this year are self-seeded and for some reason are not the darker blue I usually associate with this fascinating little flower. Their colour range can be all the way from white to very dark blue, of course.
Thanks to all who have looked in and supported my efforts. I think I am likely to be back to lots of "just clicking" as we are up to our eyes with various important family matters, including George's on/off 2nd hip operation which, fingers crossed, looks at last to be going ahead but at a different hospital.
