This clematis was bought (via internet) as C. 'Venosa Violacea' and has a label attached that declares it to be just that.
I am fairly sure this is Clematis texensis; But which one?
Is it 'Princess of Wales' or 'Gravetye Beauty'. Or perhaps another?
I would have words with the supplier but alas neither OH or I can remember where we got it!

My gripe is that the supplier sent this out wrongly. Bad continuity and poor administration.
Besides, I already have 'Princess of Wales' or 'Princess Diana' (they are available under both names), in the front garden.
However, a clematis of any sort has a place in the garden and I will try again to collect Venosa Violacae.

Very similar to Princess Diana, but definitely not Venosa Violacea which is, I think, the viticella group. See the final colour when it opens? Taylor's clematis, I've found, are helpful with ident
