CNPS Los Angeles/ Santa Monica Mountains Chapter

The Los Angeles/Santa Monica Mountains Chapter is one of 35 chapters within CNPS, which is a statewide non-profit organization of amateurs and professionals with a common interest in California’s native plants. Our region includes the Santa Monica Mountains, San Fernando Valley, West Los Angeles and Santa Monica.  We have a plant sale every year in the Fall.  There is an online talk with questions and answers on the second Tuesday evening of the month. Other events include hikes and field trips, plus restoration and conservation activities. Feel free to join us at any of our events or programs.  We love to talk about native plants, conservation, restoration, and biodiversity!

Get involved! Help grow CNPS and support our mission to protect, conserve and enjoy California’s native plants and their habitats. Assisting with a team is a great way to get started. You can help as much or as little as you wish and your time allows. Volunteering may be a single task or an ongoing commitment. We are effective because of volunteers like you. Learn about how you can get involved as a volunteer! Call the chapter at: 818-782-9346 or email us at

About the Santa Monica Mountains

About the Santa Monica Mountains

Santa Monica Mountains rise above Los Angeles, widen to meet the curve of Santa Monica Bay and reach their highest peaks facing the ocean, forming a beautiful and multi-faceted landscape. Santa Monica Mountains National Recreation Area (SMMNRA) is a cooperative effort that joins federal, state and local park agencies with private preserves and landowners to protect the natural and cultural resources of this transverse mountain range and seashore. Located in a Mediterranean ecosystem, the Santa Monica Mountains contain a wide variety of plants and wildlife. The mountains also have an interesting and diverse cultural history which begins with the Chumash and Gabrielino/Tongva peoples and continues today in “L.A.’s backyard.”

The Santa Monica Mountains have a true Mediterranean climate with hot, dry summers (80 to 100 degrees Fahrenheit) and relatively cool, wet winters (40 to 70 degrees Fahrenheit). Nights can be cool any time of the year. In the summer, the coastal side of the mountains is generally 10 to 15 degrees cooler than the inland side. In the winter this pattern is reversed with warmer temperatures along the coast. Layer your clothing to be comfortable anywhere in the mountains. For safety and comfort, use a hat, sunscreen and appropriate shoes or boots.

The Backbone Trail is the premier recreational resource of the SMMNRA. The trail provides Los Angeles residents and visitors access to more than 65,000 acres of open space and natural parks. Nearly 60 miles of the Backbone Trail are in use now, and efforts are ongoing to raise acquisition and operational funds to purchase and build the remaining trail gap to tie the central/eastern link to the western trail link. Parking and/or camping is available at Will Rogers State Historic Park, Topanga, Malibu and Point Mugu State Parks, and Circle X Ranch.

The National Park Service has published a map of the Santa Monica Mountains which includes a guide to the parklands of the SMMNRA which is a must for visitors. Find it at the NPS visitor center (address below) or call (805) 370-2301 to have a copy mailed to you. Below are descriptions of many of the best locations to view wildflowers categorized by agency jurisdiction.

Wildflower Viewing Areas

All of the areas below are within the Santa Monica Mountains National Recreation Area (SMMNRA)

This northernmost section of the SMMNRA is in the Simi Hills, part of the 100 square-mile Malibu Creek watershed, where the waters that flow in Cheeseboro and Palo Comado Canyons begin their journey to the Pacific. Native plant communities including chaparral, coastal sage scrub, valley oak savannahs and live oak riparian woodlands.

This former Boy Scout camp offers many opportunities for exploration and adventure. Journey to Sandstone Peak, the highest point in the Santa Monica Mountains.

Although not a prime location for wildflowers, visitors will find trails, a riparian area, oak woodland and Western Town, a remnant of movie days. The park entrance is on Cornell Road north of Mulholland Drive.

The Peter Strauss Trail traverses chaparral and oak riparian habitats along Triumfo Creek. Late winter and spring are the best times to view native plants in bloom. Enter on Mulholland Drive just east of Troutdale Drive.
