The flora on the crystalline scree slopes at low altitude is adapted to very high temperatures which are due not only to the sun but also to the structure of the soil. Here, dark coloured stones have accumulated on the slopes, oriented like solar panels forming a group, favourable to stockage and radiation. Wild roses of all kinds, spiky shrubs thistles have hardened to this atmosphere but so have the Sweet William and the Sheep’s Bit Scabious.
