Living wall

[Thinkle]

Sort of...
I have a garden wall and in parts the top is unfinished. There are weeds growing along the top where I assume leaves etc have composted down and seeds have landed.
The bricks have big dips in the surface so it occurred to me that I could clear it out, add soil and deliberately plant something in there like creeping thyme.
Am I mad?

Round where I live it's standard practice have two-ply walls with a central core of rubble, with no capping stone. Then there's a layer of earth on the central core and the whole thing is planted up.

In my wall I have perennial candytuft, stonecrop, hyssop, marjoram, trailing rosemary, thyme, thrift, snow-in-summer, aubretia, Nottingham catchfly,, lady's bedstraw, wallflower.

Wow, thank you! That’s sounds amazing! I will look into all of those
