Avon Gorge botany

We've had a few days in Bath and Bristol catching up with friends and seeing some of the sights, including the Clifton Suspension Bridge and these wonderful cliffs alongside - St Vincent's Rocks. This site is one of the UK's botanical hotspots, supporting 30 rare plants in quite a limited area. Good sense and my wife prevented me from exploring further, but there was lots of good information and some of the plants have been cultivated on a ledge next to the path.
