Sedum didymocalyx

A small high-alpine Sedum of western Sichuan, recorded at about 3,400 to 4,500 m in the Hengduan Mountains. It expects cool, wet summers under intense mountain light and a long, frozen, dry winter, so it suits a cold alpine house or rock garden far better than a warm windowsill. Little is published on the species itself; this profile leans on the measured climate and on alpine Sedum in general.

Where it grows wild

Recorded sites lie in the alpine zone of western Sichuan, where Sedum of this kind typically grow on open scree, rock ledges and thin turf among boulders. Treat it as a plant of exposed, fast-draining rocky ground.

Climate sites sit at about 3,400 to 4,470 m; the few GBIF records carry no elevation of their own.
