It is native to the western United States, where it is known only from Utah and Arizona. It was described in 2002.There are only five known occurrences, with 90% of the population located within Mohave County, Arizona. It is threatened by open-pit mining for gypsum.

The studies are meant to assess the feasibility of reintroducing S. gierischii to reclaimed gypsum mine tailings.In 2012, it was proposed as an endangered species under the Endangered Species Act.
