Echeveria purpusiorum A. Berger is the correct and accepted scientific name of this species. It was first described as such by Alwin Berger in Natürlichen Pflanzenfamilien, 2nd Edition, in 1930. It was FIRST described as Urbinia purpusii by Joseph Nelson Rose in Contributions from the United States National Herbarium (Smithsonian Institution) in 1911. NOTE: POWO and IPNI (International Plant Names Index) do not show Urbinia purpusii Rose as a basionym.
An annotation on Tropicos says: Originally published as “purpusorum”.; Correctable to “purpusiorum” under ICN Art. 60.8.(b), (Shenzhen Code). Named after the Purpus brothers.
The genus, Echeveria DC., was named and described by Augustin Pyramus de Candolle in Prodromus Systematis Naturalis Regni Vegetabilis in 1828.

Echeveria purpusiorum is a native of Mexico, somewhere in Puebla, near San Luis Atolotitlán. It was named after brothers Carl A. and Joseph A. Purpus. Carl was a German botanist and explorer in Mexico and the U.S. and Joseph was a German horticulturalist. They were together when this species was discovered.
I brought this plant from Lowe’s in June 2014. It is very slow-growing and takes years to reach a good-sized specimen. Even though smaller, I think it looks very good.
Origin: Central and southwest Mexico.
Zones: USDA Zones 10a-11 (30-40° F)
Size: Under 6”
Light: Sun to light shade
Soil: Fast-draining. Good quality potting soil amended with pumice (50/50) or additional perlite and chicken grit (2-1-1).
Water: Regular watering during the growing period, sparse in winter.
Propagation: Leaf cuttings.
I really liked this little Echeveria but I gave up most of my plants shortly after the above photo was taken. Hopefully, someday I will find another Echeveria purpusorum and bring it home.
