CNPS Napa Valley Chapter

Napa Valley is one of 35 chapters of the California Native Plant Society. Originally formed in 1965, the California Native Plant Society (CNPS) is a statewide non-profit organization of amateurs and professionals with a common interest in California’s native plants. The Society seeks to increase understanding of California’s native flora and to preserve this rich resource for future generations. Membership is open to everyone.

Members of the Napa Valley chapter of CNPS hail from Napa, Sonoma and Lake counties. The chapter is responsible for upkeep of the Martha Walker Native Habitat Garden at Skyline Wilderness Park in Napa, sponsors local lectures and workshops, and holds twice yearly native plant sales.

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!

Chapter Activities

Martha Walker Native Habitat Garden

Volunteer Work Group

Weekly work group meets every Wednesday morning from 9 a.m. to noon. Rain cancels. Join our group of volunteer gardeners and learn about native plants while helping maintain the Garden. No experience needed.  All age groups welcome.

Please see the Volunteer Opportunities page for more details.

Field Trips

Every Spring we offer field trips and outings to hike and explore the native plants in local natural areas. Most of these are open to both members and non-members. We publish our Wildflower Hike Schedule each February and sign up to our email list for regular updates on our offerings.

Native Plant Sales

The twice yearly plant sales hosted by the Napa Valley Chapter of the CNPS are the biggest botanical events of the year! Every April and October we source a collection of native plants suitable for Napa County planting. Sales are held at Skyline Regional Park.
