Clematis 'Cassis'
Although I'm not always fond of double flowers, there are a few exceptions, one of them is Clematis 'Cassis'. In Clematis on the Web it's parentage is described as "C. Venosa violacea X unknown" but C. florida var flore-plena must also be part of the mix.
Clematis on the Web also mentions that 'Cassis' is variable depending on growing conditions, sometimes it is a bi-clour with strong central bars, but I'm glad that my conditions give it this wonderfully textured purple veining that develops in intricacy as it ages. I've broken it down into five stages, in these pictures, but it just as well might be ten or twenty, depending on how closely you may want it to be observed.

Even at each stage - the all look so different & beautiful.
