In the flora area, Keckiella cordifolia occurs primarily in the South Coast Ranges, the San Bernardino Mountains, the Peninsular Ranges, and the Channel Islands. It grows in wooded, riparian habitats and is the most mesic of keckiellas.
Individuals with yellow corollas are presumed to be mutants in which the red anthocyanins are not expressed. Individual plants may develop as weakly sprawling to climbing shrubs. The relatively long stems are not self-supporting.
