One interesting thing about Southern California is that there’s far less difference among the seasons than there is in other areas. Sure, temperature may range from 40° F to 100° F, but it’s not enough for some imported trees. And so trees that, in their native habitat, will shed their leaves in the fall, may stay green halfway through winter.
Last Friday on my way to lunch, I spotted a number of trees like this one, that seemed to have given up figuring out when fall was, and decided, "Heck with it, I’m ditching these leaves now!"
