In the mountains of Western North Carolina, the late October snow brought down all of the ginkgo leaves, before they'd turned their characteristic luminous yellow.
In the piedmont of South Carolina, the leaves are starting to turn right now. The smaller of the two trees in the garden where I used to work (and taught a class today) is a clear, wonderful yellow.
Here's an image from a couple of years ago that looks (close to) what I saw today.
In our backyard, the vivid yellow isn't quite yet there -- hopefully, we'll see it if the arctic air that's coming our way doesn't zap those leaf abscission layers (that's what seemed to happen in the mountains).
