Stone Walls; the ideal micro climate

Hairy Bittercress, Cardumine flexuosa

One of my favourite habitats are stone walls. So many pockets which offer a safe haven for all kind of species. Her are just a few of them. And most I have not identified yet. so keep the ideas as to IDs, coming via the comments box, please!
Bittercress

Hairy (Cardamine flexuosa) or Wavy ( Sagina procumbens)





Mosses:

Nice and fresh green and sienna moss.




And this kind of moss:

At the other side of the village, along the coastal road, it is all dried up and poorly looking. I don't know enough about Moss yet to tell what caused this.


Early leaves of? Herb Robert, Geranium robertiatum perhaps? It is the hairs and the feel which remind me of good old Robert; in a stage before it starts shaping into that classic leaf shape they got.

Suggestions to the ID of this plant to be are welcome. They look familiar, but that is as far as I can go. Took this on the coastal road.

Barren Strawberry, Potentilla sterilis


and those wonderful Stonecrops. These succulents have fleshy leaves which can hold their water longer.







Don't you love the colours of these? This orange/pink is very cute, as is the shape!






What is so amazing about all these plants (in my view), is that get hardly any nutrients from the soil, like other plants, the soil they grow in is minimum, really. Thinking about plants growing in or upon walls recalls species like Ivy and Ferns of course. But have a look around you; there are so many more fighting for their little niche.

and these are just a few of them!
Sorry if I overdid it on the photos. As I said before, Blogger gave me problems in uploading my pics.
