Dudleya palmeri occurs on slopes and cliffs from the Santa Lucia Mountains in Monterey County to the Santa Monica Mountains in Los Angeles County. The populations grouped together, somewhat arbitrarily, as D. palmeri are high polyploids at three levels, on the fringes of the D. cespitosa complex, with wide leaves and red to orange corollas.
