Get your hiking boots ready — it’s wildflower season!Wildflower guide from POST

It’s time to get out on the trails and experience one of the best parts of spring in the Bay Area! And, with a little rain in the forecast again, it looks like this could be another great year for our wildflower displays.

To make it as easy for you to find them, we put together this field guide: Wildflowers of the Peninsula and South Bay. It will help you find the best blooms in our areas. Grab your copy!

For me, learning about a new wildflowers is like making a new friend. Something about knowing a plant’s name and story changes your experience with it and heightens your appreciation.

But probably the best part about the spring wildflower blooms are those big, showy blankets of flowers where the ground is exploding with color.

Where to find the best wildflower blooms?
