No, I have C. Durandii in my own garden, and this is not it.

The shape, but not the color, reminds me of Arabella. Does this one cling with leaf petioles or is it one of the ones that don’t climb on their own?

Looks like some type of x diversifolia, or an integrifolia-viticella hybrid.

Thanks, all. It does climb on its own. My original post would only allow me to post 3 photos. Here's the fourth - it's growing up a trellis.

It is stunning!
