A succulent perennial with thick linear leaves carried in rosettes or tufts at the ends of the branches. There are no dead leaves on the stems below these clusters (in contrast to the similar Sedum forsterianum). Flowers are yellow, star-shaped, produced in heads.
An introduction from the European continent. Occasional on old stone walls.
Often confused with Sedum forsterianum which grows in the same sort of habitat.
All names: Sedum rupestre L.; Sedum reflexum L.; Sedum glaucum Haw., non Lam.
