These were shot yesterday in our backyard. To my great surprise, I discovered a willow tree with fully developed catkins a week ago. There were hundreds of them on all the branches. I'm used to seeing grow on willow trees starting from mid March at earliest. Climate change?
My daughter is recovering from a flu and I bought us these anticipating that at least one of the rest of us might catch it, too.
Care to take a guess as to what these are?
