I have an unknown variety of clematis which after about 5 years is 15 ft tall and starting to cover the house wall growing along an electric cable. I am going to put up wires so it can cover the house wall but would like another clematis to grow on the other side of the same, south facing house wall. I fancied tangutica but it may be a bit too vigorous and I don't want to be on ladders every fortnight cutting it back.
Can anyone identify the one I've got? It has bell flowers about 3 cm long and has a rather undistinguished pale dirty green colur but the inside is speckled purple more like a snakeshead fritillary
