California Native Plant Week

Celebrating One of the World's Biodiversity Hotspots

Did you know that California has more native plant species than any other state in the nation? California's incredible plant life makes it not only one of the most beautiful places on Earth but also among the most important contributors to the world's biodiversity. That's why, in 2010, the California State Legislature designated the third week of April to be California Native Plant Week.

Now, we celebrate this important week each year with a wide variety of events up and down the state, including guided hikes, lectures, native plant sales, garden tours, and more!

Check our calendar of events to see what's happening year-round!
