THIS AUGUST I’VE BEEN in and out and roundabout and back and forth. I’ve spent more time on the Long Island Expressway, it sometimes seems, than in my much-loved house in Springs (East Hampton), N.Y. And I’ve fallen down the job of documenting my garden. For that I have a novel excuse besides the fact that I haven’t been here as much as I’d like: the weather’s been too good! Decent garden photography on a sunny day, in the dappled shade of tall oaks, is near impossible. But the other morning, I woke at 6, stepped outside into a misty morning, and ran to get my camera.
