Thanks for the pictures. I was hoping that Volceau would be more red and less purple. Regardless of its shade, it will be a stunning contrast to all the other clematis I see growing in lawns here abouts, which are blue.

Last year at this time I planted a locally available clematis. There was no name tag on it. So I have no idea what it is. It has blossomed now, and I have attached a photo. How do we go about identifying it?
