(Click on underlined title to see more) Centaureum venustum, pink flowers, blooms Spring to early Summer; in dry open exposures usually gets around 3 to 6 inches tall, more where it gets more water or part shade.  Yellow flower in top photo appears to be a young stage Chaenactis glab. in bloom, and in-bud Deinandra(both shown separately further in this blog).  Green bushes in bottom photo are Eriogonum fasciculatum(white flowers) and Artemisia californica(as best I can tell from the photo).
