Please Don't Eat the Daisies

Susan loves Daisies, so it is not surprising that we have a Shasta Daisy plant in the backyard. I even gave Susan a vase for her birthday that is just perfect for Daisies. By looking at this picture you might think that the flower missing its petals is old. The truth is, it was attacked yesterday by Tillie. I was busy picking up leaves and bark off the grass and when I turned around she was pulling the petals off the flower, one by one, and having a fabulous time!
My goal is to have enough flowers survive to fill Susan's vase before fall. Now, if I can just convince Tillie to cooperate.
