The valley is rapidly 'greening up' as we say, the forest slopes washed in yellow-green colours as the trees, especially the Sugar Maples first, start to wake up and unfurl their leaves. But actually, much of that yellow-green colour is not the leaves, but the flowers. Yes, trees have flowers (how else would they get seeds), and in most cases the flowers precede the leaves, if only briefly.
This is that magical timme in the woods (if I could get there), when the spring ephemerals bloom, all those spring wildflowers that we love. The sun still shines through the largely leafless canopy, but the forest floor turns green.
Here's a single Sugar Maple out on the golf course, beautiful-green.
