As I’ve mentioned before, spring is farther along downtown and in Crystal City than where I live. Which means that when I strolled down the tree-lined stretch of Crystal Drive that leads to my office this morning, I was not seeing winter-wan trunks without a hint of green. Instead, I was walking beneath baby shade.

Baby shade comes from trees just leafing, still unsure what they’re meant to do. They are uncurling, unfurling, making themselves useful not just to the plant in general but also to the pavement below.

We on the pavement are remembering what it’s like to amble beneath a great arched umbrella of greenery: how it cools us and calms us, how it intercedes between heaven and earth.

Baby shade is wan and tentative, but it is all we have now, and it is precious in its fleetingness.
