California has an amazing variety of wildflowers. Here’s my collection of California native wildflower photos, gathered from all over the state, but with an emphasis on Northern California (where I live). You may also be interested in my Wildflower Hikes page, where I write about some of the hikes you can take to find these wildflowers. All photos are available for purchase in a variety of formats.
“Endemic” indicates that the flower is found only in California.
