This species occurs from sea level to up to 1450 meters in elevation on deep to shallow volcanic [[Loam|loams]] or clays to decomposed granite soils, on well-drained sites on hillsides, mesa, and alluvial plains.<ref name=":Henrickson" /> It is found from the vicinity of [[San Quintín, Baja California|San Quintín]] in [[Baja California]] south to the [[Tres Vírgenes]] complex of volcanoes in [[Baja California Sur]]; a notable concentration is the [[Boojum forest|Boojum Forest]].<ref name=":2">{{Cite journal|last1=Rebman|first1=J.

On mainland Mexico, it is also found in a small area south of [[Puerto Libertad, Sonora|Puerto Libertad]] in coastal [[Sonora]]. The annual rainfall within its region only averages about 73 to 140&nbsp;mm, mainly from January to April and in lesser amounts in August through September. Rainfall is unreliable and sometimes years may pass without heavy rainfall.<ref name=":Henrickson">{{Cite journal|last=Henrickson|first=James|date=1972|title=A Taxonomic Revision of the Fouquieriaceae|journal=Aliso: A Journal of Systematic and Evolutionary Botany|volume=7|issue=4 |access-date=}}</ref>

The peculiar distribution pattern of the mainland boojums{{clarify|date=December 2020}} has led Mexican botanists to conclude that they were probably transplanted to the mainland by the indigenous [[Seri people]], who lived in this area and still live on communal property south of this location{{where|date=December 2020}}. The [[Seri language|Seri]] name for this plant is ''cototaj''  {{IPA|sei|ˈkototax}}.<ref>{{cite book|last=Moser|first=Mary B.|url=http://lengamer.org/admin/language_folders/seri/user_uploaded_files/links/File/DiccionarioSeri2005.pdf |archive-url=https://web.archive.org/web/20070628052611/http://lengamer.org/admin/language_folders/seri/user_uploaded_files/links/File/DiccionarioSeri2005.pdf |archive-date=2007-06-28 |url-status=live|title=Comcáac quih yaza quih hant ihíip hac: Diccionario seri–español–inglés|author2=Stephen A.

Given this belief, the hypothesis that the Seri people transplanted it is doubtful.<ref name="sallyhemming" />
