Came across some Comfrey plants growing close to the riverbank at Low Stanners, Morpeth. With the flowers Azure blue and the sepals divided less than half way I knew it wasn't Russian Comfrey which is familiar along our waysides these days. I thought perhaps it was Caucasian Comfrey a naturalised plant that is found in some parts of the country and sent a pic to the county recorder. He has sent it to Clare O'Reilly, an ecologist from Haltwhistle who thinks it maybe Caucasian or Norfolk Comfrey but will need an uprooted whole plant in May/June to analyse. So I''ll have to wait a few months to find it's true identity. Whatever it turns out to be or where it originated from it is a good local find.
