Sedum nanum

A dwarf high-mountain stonecrop from Iran and Türkiye, recorded around 4,000 m in the Zagros. It lives with snow-covered winters and a bone-dry, intensely sunny summer, so it needs full sun, a cold winter and very sharp drainage; whether it is annual or perennial is not well documented.
