A leading voice in native
plant appreciation.

since 1965

Since its beginnings, the California Native Plant Society has been a leading voice in plant science and native plant appreciation, making it one of the foremost native plant organizations in the world. We are a 501(c) 3 non-profit dedicated to conserving California native plants and their natural habitats, while increasing the understanding, enjoyment, and horticultural use of native plants. We work closely with decision-makers, scientists, and local planners to advocate for well-informed and environmentally friendly policies, regulations, and land management practices. See our Mission and Vision statement.

Our Mission

To protect California’s native plants and their natural habitats, today and into the future, through science, education, stewardship, gardening, and advocacy.

We envision a future

In which native plant diversity flourishes.

Where all people have access to native plants in both the built environment and the wild.

Where people of all backgrounds play a vital role in the conservation of our native plant heritage.
