Living Wall at Balcaskie

The ancient walls of the terraces in the garden at Balcaskie provide a habitat for many different plants.

A small white verbascum growing up the wall.

Yellow corydalis was probably the most prolific plant.

There is also a lot of this pale purple flower. At first I thought it was an aubretia, but I now think that it is Erinus alpinus aso known as fairy foxglove.
