There ought to be a name for the day, in temperate climates, that the trees leaf out. (It would not be the same date each year & it would come earlier the further south one went.) Here in St. Lawrence County, that day was yesterday. The world went from shades of gray & brown to shades of green. The birches are & willows are an intense yellow-green, the maples a kind of dusky green, except for the species that leafs out first bright red, then goes green as chlorophyll pumps into the leaves. The roadsides have gone from dust & plow gravel to grass overnight. As I say, there ought to be a name for this particular day of each year.
