The species, Sedum telephium, commonly known as Stonecrop, is native to most of Europe (including the UK). Sedum telephium is synonymous with Hylotelephium telephium.

The etymological root of the binomial name Sedum is derived from the Latin sedo ’settle’, a name used by Pliny describing how the cushion species of this genus hug the rocks. Telephium is from the Greek name thlefion, a name given to plants capable of indicating reciprocated love.
