Distribution and habitat
It is native to northeastern California and adjacent sections of Oregon, where it grows in sagebrush and wet, open habitat in scrub, forest, and woodland. Once thought to be extremely rare and vulnerable, the plant is actually locally common in areas where the soil has been recently disturbed, allowing a probably large seed bank to germinate.Meinke, R. J. (1995).

Despite its annual population sometimes running into the millions, the plant is threatened when large-scale disturbances occur.{{Cite web |url=http://northcoastcnps.org/cgi-bin/inv/inventory.cgi/Go?_id=mimulus_pygmaeus&sort=DEFAULT&search=Mimulus%20pygmaeus |title=California Native Plant Society Rare Plant Profile |access-date=2011-07-25 |archive-url=https://web.archive.org/web/20120326192220/http://northcoastcnps.org/cgi-bin/inv/inventory.cgi/Go?_id=mimulus_pygmaeus&sort=DEFAULT&search=Mimulus%20pygmaeus |archive-date=2012-03-26 |url-status=dead }}
