Clematis suggestions please
I have a Clematis viticella 'Purpurea Plena Elegans' on my archway. It has flowered quite well but is viewed predominantly against a red brick wall so it doesn't show up much. I'm thinking of planting another as a companion to add the oomph I would like. Has anyone any suggestions for a variety which would make more of a splash of colour? I've been looking at Thorncroft clematis and there's so much choice. Thank you.
