Our house in Pasadena is situated in a canyon surrounded by arms of the San Rafael Hills. The hillsides are covered by vegetation typical of the foothills of the San Gabriel Mountains to the north, with many plants similar to those in the mountain chaparral. These hills provide a generous showing of wildflowers during the spring and early summer months. This page contains the results of a wildflower survey by Graham during the annual flowering season beginning in January 2013, based on a weekly walk on the hillside. (Click the thumbnail at the left to see a summary through September 2013.)

The weekly walk is not always on the same day of the week. Originally it was mainly on a Saturday of Sunday. Later it was mostly on Monday. Occasionally it would be Tuesday or Wednesday. For this reason, the survey week is defined as beginning on Thursday. The nominal plan for each walk was to explore the hillsides to the immediate north and west of our house.
