Seakale - the RHS site says PC is LL and that viticela is a pseudonym. This academic website which I use to check clematis descriptions for flowering epriod and pruning groups also says PC is in the LL group - http://www.clematis.hull.ac.uk/new-clemdetail.cfm?dbkey=37
have to say that in Belgium I treated all group 2s as group 3s for pruning as winter usually killed off al their top growth so they behaved like vitciellas and flowered thru summer rather than in May/june.
