I inherited this lovely clematis when we moved here. It didn't look great last year and I cut it back quite hard (probably at the wrong time) but I've got a few flowers blooming now.
I thought it looked a bit like C. Tsukiko, but that's a late flowering variety. It's also similar to C. 'Pat Coleman' which would be in flower now, but I think the petals on mine don't have the same crimped edges. Any ideas?
