[1] It is found in Portugal, Spain, France, Italy, and Mediterranean islands, as well as Turkey, Israel, Libya, Syria, Tunisia, Algeria, and Morocco.

Leaves are overlapping, oblong to elliptic, with pointed tips, somewhat thickened, sometimes flattened and spurred, reaching up to 20 mm in length.

[5] When in bloom, Petrosedum sediforme produces upright flowering stems that range from 25 to 60 cm tall.

The small green triangular sepals (the outer parts that protect the flower bud) are about 2–3 mm long.

The stamens (the parts that hold pollen) have white filaments with a rough texture at the base and yellow anthers.

[1] Petrosedum sediforme is difficult to distinguish from P. rupestre, P. ochroleucum, and P. montanum based solely on vegetative traits.

[2] Spanish plants with brownish or olive-green tones are remarkably similar to some Israeli specimens—despite originating from the opposite end of the species’ range.
