I have been National Collection Holder of Clematis Viticella since 2005 and I am always on the lookout for rarer, sometimes almost obsolete, members of this wonderful family. Never did I imagine that I would be offered a new 'double' form, the only other two doubles in my Collection are C. viticella 'Flore Pleno' (syn. C. 'Mary Rose') and C. 'Purpurea Plena Elegans'.
Talking to Brian Collingwood many years ago, he mentioned that Harry Caddick, who with his family ran the famous Caddick's Clematis Nursery at Warrington, quite near to us, here in UK, had acquired a new double viticella which had been found growing in a customer's garden. I knew Harry quite well as we had visited his nursery, and he and family had been to our garden, several times in the past.
Harry kindly passed on a plant to me and I now grow and propagate this variety.
Almost 15 years after this new variety was found, I registered it with RHS.
I also passed on a piece to Manfred Westphal who has the wonderful clematis nursery in Germany.
Mary and husband Martyn called in to see us several times, a lovely couple. Mary is a real clematis enthusiast and I am so pleased that this new variety bears her name.
