A Little-Known Sedum
Sedum kimnachii is a succulent subshrub in the stonecrop family, one of the many quiet, fleshy-leaved members of Crassulaceae. It is not a plant much written about, but botanically it is a settled, accepted species rather than a passing name.

From Central Mexico
This species is native to central Mexico, where it grows as a succulent subshrub in the temperate biome. It was first described and published under this name in the Kew Bulletin in 1999, credited to V.V. Byalt. It has since turned up as an introduced plant in France, Great Britain, and Ireland, and the RHS lists it too, though under a couple of older names it has worn along the way, including Sedum confusum (misapplied) and Sedum decumbens.
