On a road i drive up most days there is a front garden with a dry stone
wall. Growing over the wall is a mass of green foliage with wonderful
purple flowers. (trailing about 50cm+ down)

I have only seen these from a distance, but the foliage looks like
small green leaves and so does the flower.

It also appears to be growing thru the cracks in the wall.

I would love to get some of this in my garden wall, but unsure what it
is.

Any ideas anyone?

At this time of year, usually Aubretia
