Jepsonia malvifolia is uncommon and occurs on all of the Channel Islands except Anacapa, Santa Barbara, and San Miguel. Individuals of this species produce flowers that usually last longer than those of the other two members of the genus. Prior to 1992, this species was in decline on Santa Cruz and Santa Rosa islands because feral pigs ate the fleshy caudices. Populations have apparently rebounded to some extent since removal of the pigs.
