California redbud, Cercus occidentalis. This shrubby tree has gorgeous red buds that look ready to burst into bloom. Here's a picture of one blooming. Great color. I'm thinking this would be a nice addition to the yard.
This beauty is a malva rose or Lavatera assurgentiflora. It is in the mallow family.
These hanging clusters of flowers are pink flowering currant, Ribes sanguineum glutinosum. The link here is to the Yerba Buena Nursery, which is off Skyline Blvd. just south of where Woodside Road crosses it. It's a very cool place to visit and a great place to see and purchase California native plants. The road driving in is narrow and it drops off very steeply, so drive carefully. They're having a tea party there on March 15.
Lastly, here is prickly-phlox or Leptodactylon californicum. It does look like the leaves are prickly.
No pink flowers here, but I thought this was sort of interesting. It's mistletoe (as in kissing under the...) growing out of the trunk of a cedar. It is a parasitic plant.
