Native to Southern Eruope from about 200 to 2800 m, it has neat stolinferous rosettes with a red hue, and ciliate ("Hairy") leaf margins. It naturally grows in rocky outcrops and cliffs, but it became well known in ancient times since it was typically found on roofs, hence the name "tectorum", meaning "of the roofs"
