The Teton Chapter of the Wyoming Native Plants Society will host former National Park Service Ranger and naturalist Katy Duffy at the Teton County Library this evening, September 27th, at 6pm. She will talk about "The Wildflowers of Yellowstone" and how different aspects of landscape influence the types of flowers that grow and when. She has spent the last several decades in both Grand Teton and Yellowstone National Parks and describes her appetite for the beauty of wildflowers like a craving for ice cream - insatiable.
