Touch of blue

A planned car photoshoot at the end of last week was thwarted by damp and misty weather, so today’s positive forecast was very welcome. A fine day, and lengthening hours of sunlight, enabled us to cram two car twin test photoshoots into one day. On the latter one this afternoon, I spotted this beautiful blue agapanthus randomly stuck into a fence-top at the location. Wonder why it was there?
