This beautiful Leather Flower was growing at the Reader Rock Garden a few weeks ago.

Added 7th January 2011, when I compared this flower with a photo of Clematis 'Roguchi' posted by Doug (dougwaylett). I thought the two flowers were perhaps the same, but::

"Thanks Anne but it isn't the same clematis. Clematis 'Roguchi' never opens this much and the stalks are a much darker purple. In my photo of C. 'Roguchi' that is as open as the bell gets. This one may well be C. durandii one of the parents of Roguchi and a much easier to come by clematis that can be obtained at most garden centres. C. durandii is also one of my favourites and is one of the bluest of the blue clematises. It may also be one of many other Clematis integrifolia hybrids. I have never seen Clematis 'Roguchi' for sale at a local garden centre. The only person who sell it in Calgary is Rod Shaver at Rundlewood Gardens."
