Clarkia similis is known from southwestern California and northern Baja California, Mexico, mainly in the South Coast, Transverse, and Peninsular ranges, from Monterey and San Benito counties in the north to San Diego County in the south. Reports from the Southern Sierra Nevada Foothills in Kern County and the Sacramento Valley in Tehama County are not confirmed.

Clarkia similis is a tetraploid species derived through polyploidization following hybridization between C. epilobioides and C. modesta.
