Sedum alamosanum

A small northwestern Mexican stonecrop of rocky slopes and cliffs from Baja California Sur across Sonora, Chihuahua, Sinaloa and Durango. It expects a very dry, bright spring, a hot wet summer monsoon and mild dry winters, and it is easy in a gritty mix with a dry spell in spring.
