A perennial herb which occurs as a casual on walls, rocks and dry waste ground. Despite reproducing from seed, it only rarely persists. Lowland.
Introduced into cultivation in 1710 and first recorded in the wild in 1912, A. saxatile is very commonly grown in gardens. It is unevenly recorded, as botanists differ in the tendency to which they record species established on garden walls.
Native of C. & S.E. Europe and S.W. Asia.
