We realise there is a vast number of Clematis varieties and hybrids and this one might not be an easy one to identify as it was planted around 1996. We have spent ages looking on the net to no avail.
We live in New Zealand and the plant is having a second life so to speak. In its first life it was robust right from the start, so much so we often had to cut it back from clogging the roof gutters. So it grew to 3 metres easily and would be able to go higher and wider. It's second life started last year when we had no option but to transplant it, chopping it back severely to do so. Following advice gleaned from the net we got it right and it's flourishing. We were thrilled we didn't kill it. Maybe you can't kill Clematis.
The main reason for asking is we would like to know which pruning group it belongs to. It is only now after all these years we have found out about pruning groups. Obviously it has done well despite our ignorance ; but as it has done us the kindness to live, we should do our best for it.

Any information that could steer us in the right direction would be appreciated.
