About 3-4 years ago we - Chris and I - bought a plant of Clematis cartmanii. It turned out to be a very attractive climber and so we bought a second specimen. What at the time I hadn't realised is that this 'species' is a hybrid, the parents being two New Zealand species, Clematis marmoraria and C. paniculata. Furthermore the cross between these two species has been made on a number of occasions, each time with a slightly different result. The consequence is that we have finished up with two forms of the hybrid.
