I've also posted this question on the Clematis forum. Maybe someone here can take a guess or even knows what this is?

I bought it a few years ago at a box store. Actually, it was in a box that was labelled 'Belle of Woking." I had my doubts about that. The plant had a single teeny stem and no buds. With a plant that size I would normally pot it up and wait a few years to transplant. But I put it in the ground next to a Nelly Moser and forgot about it. Last year I inadvertently, but perhaps luckily, cut it back when I was weeding.

And so here it is a few days ago next to Nelly. The small, bell-shaped blossoms are 2 & 1/2 inches wide when opened with a red-maroon stripe down the back of each petal. The true color is a deep purple red as in the bottom blossoms, but sunshine altered the photos.

A close up showing its slightly rippled edges.

Next to Nelly, this unnamed Clematis is golden in the center. The flowers open from a tiny bell-shaped bud less than an inch in size.

The outside of the blossom is not really as pink-looking as in this photo.

I know there are thousands of Clematis, but perhaps someone recognizes it or could give me an idea of its group.
