Hi, George, I was out in our garden watering near sunset yesterday and noticed that the sunflowers, although not in flower yet (buds are maturing, visibly, daily), the buds follow the sun. BTW, those "visitors" in our garden are really resilient. One plant grew up between cracks in the garden walk, making it impossible to remove. It is right on the path, the only path, to carry the green can (yard waste) to the curb for pickup. That plant has been run over weekly, keeps on picking itself up and growing some more. I wish that everything in our garden were that spunky! Ron
