It's really more like white slush. But, I'll admit it looks pretty until it hits the ground.
Interestingly, it looks more snow-like when it clings to tree branches.
In The Waste Land, T.S. Eliot wrote, "Winter kept us warm, covering Earth in forgetful snow." It's not hard to see what he meant: For a moment, I can actually forget that leaves have died and fallen from that tree.
I also can forget, for a moment, that one day this tree, and the one in the first photo, will be green again. Or, at any rate, I have--however temporarily--no need to remember that.
