Thanks, all.
Russ, it was a bit of both. We'd just arrived at the château where we to spend the week (and where we held our wedding blessing ten years ago). I looked up and saw an interesting sky, so I went up to the bedroom, set up and waited. The sun set very quickly, which was a shame as the sky remained interesting for a while after the light had left the village church. It's an idyllic spot for a holiday.
David, fair point. It would take a rather brutal crop to remove all of that plant (a garden bush, not a weed), but the upper bits might be (neologism alert!) outclonable.
