There are a lot that color. Carnaby, Dr. Ruppel, Nelly Moser.
Wow, I look at those 3, and they all look somewhat alike. How does one ID these for sure?
You need to compare leaves and seed heads.
Janet is correct..There are many attributes of a Clematis that when combined tell the true Identity..besides Leaves & Seedheads..there is the bar,tepal,connective and Anthers..along with the back side of the tepals..recurve..fading ...etc..I am kinda leaning towards "Nelly Moser" because of the white connectives..Jeanne
Is there a particular shot I would need to take that would help?
A shot of the back.
Here is a pic of the back side of the bloom. I hope this helps someone to ID ut.
