In this section we offer opportunities and resources to experience the wonderful array of native wild plants in Marin County for all ages and levels of botanical expertise. Field trips are held throughout the year, but especially during the Spring and Summer when many native plants have their peak bloom. Please join us and experience what a wonderful bounty Marin has to offer.

Plant lists for many locations in Marin are available as an aid to identifying the plants that you may see. Flower Sheets offer a single page of twenty thumbnail images of plants for selected areas and can be downloaded. Species Guides are available for Marin and the San Francisco Bay Area which have photos and descriptions for various species and communities. Many other resources, such as Rare Plants of Marin, Plant of the Month, Marin Flora, Plant Identification, Wildflower Reports, Native Plant Books, and Plants of the Season are listed under the “In the Wild” menu.
