Lots and lots of wildflowers around at the moment.  Its good having an app on the phone to help identify them.  Apparently this one is a Musk Mallow.  My camera was behaving very oddly  this morning.  It just didn't want to focus, was hit and miss.  Did all the usual checks and then reset it to factory settings.  Didn't make much difference... then later on it was ok again... very strange.
