All wildflower photos are taken with permission from the excellent collection of California wildflowers by the late Brother Brousseau, formerly of St. Mary's College. His photographs and those of his successors have been digitized and are maintained as part of the Berkeley Digital Library Project at UC-Berkeley. The database contains thousands of his photos and is fully searchable. This is, of course, just the tip of the iceberg (or iceplant, if you prefer).

The wildflowers in this table can be seen throughout Bay Area trails. Excellent trails include those at: Mt. Diablo State Park, San Bruno Mt., Mt. Tamalpias and Tilden Park. For a thorough description of the latter check out the East Bay Region Park District site.

If you wish to learn more about native plants, you can go on a hike with a local chapter of California Native Plant Society. Their members are usually experts at wildflower and plant identification. To help you remember you may wish to create a wildflower list and corrleate them with photographs. Another possibility is to visit a local botanical garden, such as the Regional Parks Botanical Garden at Tilden, or the U.C.-Berkeley Botanical Garden. The former is devoted entirely to California native plants, while the latter has a wonderful native plant section. It is possible to become a docent at either garden - that has certainly helped me familiarize myself with local flora.

Spring 1999 Update
This spring, like many others in recent memory, has been unusual in that it has been quite cool and rainy.  This bodes well for a good wildflower display, albeit rather late. As of the 10th of April I have hiked in Morgan Territory, Mount Diablo, Montara Mountain and the Berkeley Hills all without seeing abundant wildflowers.  This is not to say that there isn't a lot going on out there, it's just that the flowers are delayed by a month or so due to the cool, wet weather.  This will of course change soon and if you wish to get a daily update on the wildflower scene, check out Carol Leigh's excellent Wildflower Hotsheet.

If you have suggestions of comments on how to improve this site, or if you wish to have your favorite flower added to the list, please mail
