Verdun, that sounds lovely and great to keep the interest going throughout the summer months!
Arabis is a good suggestion and the one I had in my old garden gave off a lovely scent.
The other thing that I have grown on the dry parts of my rockery are Californian Poppy, they would like the dry conditions and add a lovely splash of bright orange although you can get pink and cream varieties also. Only annual but might be worth buying a packet of seed and sprinkling over the gaps in the wall and see what grows!?...
