Of course, Autumn here is just 85 instead of 92 degrees and includes darker mornings and evenings. Otherwise you have no real idea what time of year it is. I suspect the tree in the front of the house will switch this year's set of leaves for new ones in the coming months. But instead of a big, dramatic color show - they'll just fade, shrivel and drop and almost simultaneously be replaced by new growth.
Ah, subtropical. Maybe that explains the color of the first leaf. Or maybe my glaze experiment was wildly successful. I prefer the latter.
