Moss wall

It would if you didn't want it!

I tried a mix of yogurt and mossy soil on an old sink but I think the surface was too shiny for it to take well.
(Then DH pressure washed it because he thought it was going green)

I think brick might be difficult for moss, it likes very damp stone, preferably in the shade.
Would it be possible to create pockets in the wall ( I appreciate it might be brand new) and grow saxifrage and aubretia type plants.

Does it face north?

If the wall faces south it may not work.

Hart's-Tongue ferns grew with abandon on my parents' red Accrington brick garden wall. Mind you it wasn't new build when they moved in.

Move to Argyll. Mosses and liverworts grow on everything here 😉

Ferns too.

I’d do a bit of research first, I think it might be damaging to the mortar in your wall in the longer term? It may be better to have a trellis installed and grow something up it which doesn’t attach itself to the wall instead.

I love the moss and ferns in Argyll. It really feels like a rain forest in places.

The trouble is that there is no earth below the wall - only tiny paving stones - so I cannot plant anything in the ground to grow up it; and I cannot grow anything in a tub as it would make the parking a bit of a squash.

It really is a rain forest, Aveline. Just a temperate one instead of tropical 😀

Maybe a narrow long planter would be an option? You could get one that’s only about 12 inches depth so it sticks out into your drive very little, but long and deep, that would enable you to grow quite a few things?

Would you have space for a wall planter, as used to create living walls? Just a curtain of pockets really but widens the scope of plants you could consider.
If you search for 'green wall planting system' you'll find lots of ideas.

Just don't! If a brick wall is damp enough for moss to grow - it's going to deteriorate pretty rapidly. I agree with Casdon in that trellis and a non-clinging climber would be better. Do bear in mind, though, that new bright red brick will soon tone down into a more brown colour.

Callistemon21, my friend tried the yoghurt method to change her hated pink patio. When she went on holiday, her neighbour was watering the plants - and kindly jet washed it back to new!

DH was being really helpful. It was his mother's sink and he wanted it to look white and shining!!
I've given in now. Once I planted it with small succulents but the squirrel got in there, dug around and threw them over the patio, where little bits got stuck and grew in the cracks.

we attacted small hose (like aquaruim hose) along top of wall as drip line
mosses an such space aroung and grew well and a month get going an removed hose as it took of its self

did one a around our stone fireplace too

I have googled "green wall planting system and found several options that might work - thanks for the idea.

My friend sprayed a thin yogurt mix on some statues in her garden -which I expect were concrete. I did similar with some terracotta - mine didn't grow moss but does look more weathered.
