The species is geographically isolated within Sect. Graptopetalum, as all other species of the section are located between Nayarit/Durango and Arizona.


Two somewhat different clones are in cultivation. Plants resemble small echeverias, they produce long stolons with new plantlets and are fine in hanging baskets.
