I love the linear quality of vines and they stand out among the upright stalks of so many prairie plants. I may have to wait for summer blooms to identify this one, though. Unless you know. If so, please let me know in the comments. Guesses welcome.

Still appreciating the prairie photos, and appreciating beholding beauty this time of year, when a lot of people struggle with finding some.Thank You.
Thanks. It takes a little more effort to find as winter wears on but that makes it that much more worth while.
