I’m always grateful when Iowa naturalist Eileen Miller shares her photography on this blog. Bleeding Heartland readers have seen her incredible eye for detail in wildflowers such as golden corydalis, hoary puccoon and fringed puccoon, marsh marigold, snow trillium, hepatica, blue cohosh, and pasque flower.

The strong coarse leaf fibers can be extracted to make cordage.
