I was absolutely delighted to find this yellow beauty in bloom in the woods earlier this week.I knew it as a Dog-tooth violet but it goes by many other names as well: Trout -lily,Fawn lily, both names are derived from the spotted leaves of this woodland plant And its also called Adder's tongue. A clue to the origin of this name lies in the visual red stamens seen at the center of its yellow petals.Part of the border shows what looks like a white tooth. the name dog-tooth is rooted in the root of this wildflower, which looks like a canine tooth. I dug one up once to verify that and its root does look just like a dog's tooth. this second kaleidoscope I call 'the Adder's mouth!! so much fun playing with this wildflower's name.
