Of Interest: Recently California has had not one, but TWO successive Spring Seasons. The rains started unusually early in the Fall (October), unleashing the first burst of new greenness and life. Coming weekly or biweekly for the next several months, the rains generated the second Spring in February, since the first flush of growth had had time to set seed and were ready to start a new life cycle. This has happened twice in my lifetime.
During drought years, lacking clouds, there sometimes is "too much" strong daylight to trigger the proper onset of Fall. And if we have no strong windstorms in such seasons, you will find deciduous trees that have retained their leaves all the way into Spring, until the new-growth leaves push them off! I love California!
