Wildflowers in the Santa Monica Mountains, San Gabriel Mountains and other open areas of Los Angeles County bloom each spring adding splashes of color along the area’s trails. Some flowers can be seen into the summer and fall. Below are some examples of common wildflowers that appear beside Los Angeles hiking trails. The flowers are listed alphabetically with a link to the trails where they were seen. For a broader reference visit the Santa Monica Mountains wildflower finder.

The flowers pictured are California natives with one exception: gazanias come from South Africa. Pretty though they may be, introduced species compete with native plants and should be eradicated in wilderness areas.
