Get Involved!

Help grow CNPS and support our mission to protect, conserve and enjoy California’s native plants and their habitats! Our chapter is entirely volunteer-run, so there are lots of opportunities to get involved. The Napa Valley chapter of the CNPS needs you!

We have a number of volunteer opportunities to suit your schedule and interests.

Volunteer Opportunities

Martha Walker Native Habitat Garden Steward

Meet other local gardening enthusiasts and learn to propagate and cultivate California native plants. Volunteers help with upkeep for the Martha Walker Native Plant Garden, where we grow native plants for the garden, our April and October yearly plant sales.

A weekly work group meets every Wednesday morning from 9 a.m. to noon at the Garden in Skyline Park, 2201 Imola Avenue in Napa. No experience or native plant knowledge required – you will learn by doing.  No need to contact us first; just show up with water, a hat, and gloves.  We have the tools you need.  It is a fun group, and the Garden will thank you. (Rain cancels.)

Special one day garden projects can be arranged for work groups, scouts or anyone interested. To coordinate a custom work day, contact our volunteer coordinator at

Plant Sale Volunteers

We are always recruiting volunteers to help with the Spring and Fall Plant Sales.  Learn about the different plant communities and the plants that grow within them. You will learn this and more by volunteering at the Sale. Volunteers help organize plants before and during the sale and help attendees with the plants they want to purchase. You do not need to be a native plant expert to help!

To sign up, contact Sandie Hewitt: or (707) 815-0771.
