Darren, aubretia is a low cascading perennial. Flowers in spring. However, check out helianthemums......rock or sun roses. They are evergreen, flower for much of,the summer in colours from white to red to yellow, etc. my favourites are the Wisley varieties ...wisley pink and wisley primrose both having lovely greyish foliage.
In such a wall, ??ou can grow all manner of things. Alyssum is a lovely yellow cascading plant that will set off purple aubretia. Arabis is a white or pink....prefer the white.....cascading plant,
Sorry Dean......please Darren DONT grow cerastium. It is a thug that seeds EVERYWHERE. I know some people like it but it will overwhelm your garden.
I have a couple of walls filled with aubretia, alyssum, Helianthemums, mesembryanthemums, Arabis, osteospermums, all cascading down the low walls. Lovely in spring and summer. You,will have a riot of colour.
