Phedimus kamtschaticus

A hardy, clump-forming stonecrop from rocky slopes of the Russian Far East, northern China, Korea and Japan. It wants full sun, a gritty but not bone-dry soil and a genuinely cold winter, when the stems die back to a woody crown. It is a garden perennial much more than a windowsill succulent.

Where it grows wild

Grows on rocky slopes, cliff ledges and stony grassland in a monsoon climate with warm, wet summers and cold, fairly dry winters. Plants root into thin soil between rocks, where water drains away quickly but summer rain is frequent.

Measured records run from 42 to 668 m (median 320 m, only 12 records with an elevation); floras give rocky slopes at roughly 600 to 1,800 m. Northern populations reach sea level in a much colder climate.
