The blue stonecrop is an annual plant with a mainly southwestern Mediterranean distribution, present in Sardinia and in Sicily. It grows in rocky and gravelly sites, on primitive, acid or sub-acid soils that are dry in summer, on siliceous substrates, from sea level to about 800 m, with optimum in the Mediterranean belt. The species is common at the edge of the temporary ponds of Sardinia, in contact with rocky outcrops. The genus name is of uncertain etymology: it could derive from the Latin 'sedeo' (I sit down), due to the prostrate habit of many species, or from 'sedare' (to calm); the species name refers to the pale blue colour of the flowers. Flowering period: February to May.

Italian name(s): Borracina azzurra (Italia), Racinedda di lu Signuri (Sicilia, Modica), Racinedda di lupu russa (Sicilia, Etna), Sedo ceruleo (Italia), Sempervivu azuru (Sardegna).
