Aubretia on the old wall at the farm

As you move into a new garden you look around seeing which plants are thriving in the neighbours gardens.  Also you notice where people have shared cuttings as the exact same plants are seen.  I’ve started planting aubretia in a wall to try and get this beautiful effect.  I love that this is all the  same colour, a lovely neutral mauve.  I, being more of a magpie have put in five different purples....I think it self seeds a bit.  I hope so.
