Sedum radiatum
A small, short-lived stonecrop of rock outcrops in northern California and southwest Oregon that grows through the cool, wet winter and spring and sets seed before the dry summer. Grow it cool, bright and lean, and expect it to behave like a winter annual or biennial rather than a permanent mat.
Where it grows wild
Thin soil pockets, gravel and moss on rock outcrops, road cuts and open slopes in chaparral and mixed conifer country, often on serpentine or volcanic rock. Seeps keep it wet in spring; it dries out completely by midsummer.
Recorded from 225 to 3353 m, mostly around 1000 m in the Coast Ranges, Klamath and Sierra foothills; the highest records are likely mislabelled or rare.
