Usage Guide

The Bay Area Wildflower Guide (BAWG) is a collection of my own photos and notes. It is designed to be my own reference as well as something I can point people to when I make identifications. Warning: I am not a botanist, just an interested amateur. All identifications should be taken as my opinion and not authoritative.

The BAWG is primarily for me, secondarily for you. You can use it as a reference if you like, but I hope you don’t use it as your sole reference.

Only wildflowers are covered, not cultivated flowers. I’ve also started including taxons other than flowering plants here, but in much smaller numbers and lesser detail.

The BAWG covers the San Francisco Bay Area, from the Pacific coast to corners including Mt. Tamalpais, Mt. Diablo, San Luis Reservoir, and Santa Cruz. A few other areas nearby are also covered if I visit them frequently enough. The gravitational center for my observations is probably somewhere around Cupertino.

If you find anything confusing, I have help pages.

Other Resources

Primary references include iNaturalist, CalFlora, CalPhotos, and Jepson eFlora. If you find yourself checking Jepson eFlora often, you may also want to browse the Jepson eFlora User’s Guide. When I’m identifying flowers from a hike, I often use PlantID.net to get a list of flowers known to grow in the park.

Monterey County Wildflowers covers an adjacent region, so it is often useful for bay area species as well. It has a similar organization as this guide with both photos and notes for how to distinguish species.
