Diplacus puniceus, commonly known as the red bush monkeyflower, San Diego monkey flower, or mission diplacus,[2] is a species of perennial shrub native to coastal southern California and northern Baja California.

It is characterized by a relatively small and broad corolla for Diplacus, a lack of glandular hairs, and dark orange or red flowers, adapted to hummingbird pollinators.

[3] This plant is a glabrous (free from hair) evergreen subshrub or shrub, growing perennially.

[3] This plant occurs throughout Southern California, occupying granite outcrops, openings in the chaparral, and disturbed areas, from an elevation of 100 to 700 meters.

[3] In Baja California, the plant is also found along the Pacific Coast, from the vicinity of Tijuana south to El Rosario.
