It is a job to know which plant you want identified, as there are several in the picture: It's a good idea to be specific about what you are after.
I can see Gorse (Ulex europaeus), Hogweed (Heracleum sphondylium), Cow Parsley (Anthriscus sylvestris), Bramble (Rubus fruticosus agg.) and Horsetail (Equisetum sp.).
I suspect you were after either the yellow-flowered Gorse, or the traiing Bramble or the low Equisetum in the stones.

The assumption in your last sentence is correct. Thanks
I think Ian has got almost everything except for the grass which, because of the shininess of the leaves, might just be Lolium perenne (Perennial Ryegrass)
