Copper (or Shrubby) Purslane (Portulaca suffrutescens) is blooming in some of the sandy areas in the canyon. (See page 150 in Rose, too)
And a bonus book recommendation: Life Ascending: The Ten Great Inventions of Evolution by Nick Lane. I particularly like the chapters on DNA and on photosynthesis, of course. Very well written.
