Clarkia delicata is known in California only from the Peninsular Ranges, mainly in San Diego County with outliers in Riverside and San Bernardino counties, and in northern Baja California, Mexico. Because of its limited range, it is listed as rare by the California Native Plant Society. It is a tetraploid derived from hybridization between C. epilobioides and C. unguiculata.
