The photos in this wildflower identification guide are intended to help you identify the wildflowers that you may see in Mount Diablo State Park throughout the blooming season. The photos were taken by volunteers and do not necessarily include specific features necessary to identify the flowers.

Select a color category. The color of the flower is sometimes difficult to classify for a variety of reasons (such as lighting, camera used, or device used to view the picture), so if you don't find the flower in one color category, try another. The wildflowers are then listed in alphabetical order by common name of the plant. Some plants are known by more than one common name, so be sure to check them all if you are seeking a specific name. Don't forget to click the picture to get a closer look!

Typical bloom months are also listed. Bloom dates vary from year to year depending on the weather. The same plant may bloom at different times, depending on its location and elevation.

 

Check out What's Blooming Now on Mount Diablo. This list is maintained by Steve Beatty and Steve Smith, along with our many “Flower Finders” roaming the mountain.
