About

Dudleya cymosa subsp. agourensis, commonly known as the Agoura Hills dudleya or Agoura Hills liveforever, is a species of perennial succulent plant. A rare and critically imperiled species from the Santa Monica Mountains in California, it is characterized by glaucous, gray-purple leaves, bright yellow flowers, and ascending bracts. A leaf succulent, it is found growing on west to northwest-facing open, rocky volcanic slopes.

It was formerly considered to be a distinct race within Dudleya cymosa subsp. ovatifolia, until it was described in 1987 on the basis of numerous differences that distinguished it from that subspecies, namely the leaf morphology, the branching caudex, and the morphology of the flowers and inflorescences. Although subsp. ovatifolia was split, this species has inherited its listed status as threatened under the Endangered Species Act.

Where it grows

Dudleya cymosa subsp. agourensis is endemic to California in the United States, occurring in the Santa Monica Mountains of the Transverse Ranges. It is found in Ventura County and Los Angeles County. All occurrences of this species are found in a 2 mi (3.2 km) by 6 mi (9.7 km) band along the north-facing side of the western Santa Monica Mountains, between Thousand Oaks and Agoura Hills.
