A page for wildflower and hiking enthusiast. A lot of my pictures, both wildflowers and scenery, come from the beautiful Tennessee State Parks. I use the Lady Bird Johnson Wildflower Center for my description of native plants. All non-native plants will use someone else for the description. The best way to follow this blog is to enter your e-mail address below. You will receive an e-mail that looks just like the post with all the pictures.
