Sedum danjoense

A small stonecrop known only from Japan, named after the Danjo Islands, a remote group of islets west of Kyushu in the East China Sea. Treat it like other coastal Japanese Sedum: bright sun, sharp drainage, salt-wind exposure, and mild, wet winters rather than deep frost.

Where it grows wild

Little is published beyond the description; Sedum of small Japanese islands typically grow in crevices and thin soil on sunny coastal rocks and cliff tops exposed to sea wind.

The Danjo Islands are low islets, so it most likely grows near sea level; the single measured site at 645 m in central Honshu does not match the islands.
