Here are extremely stressed flora - a pine, and a rhododendron. And then, fresh spring leaves.

Ha ha, I'm going to go out on a limb here, (horrid pun, sorry), and say, that many of those trees that have produced leaves this spring look peculiar. I haven't had time to take pictures of the bizarre fall colors emerging instead of pale, bright green, but look at these catalpas, by no means unique. They put out the leaves but they look WILTED, in MAY. Maybe I'm over-sensitive and they always do that and I never noticed - but I actually don't think so. It's like, they used all their remaining energy producing the leaves and have no moisture or strength to hold them up.
