Thanks again Chris. How would I have found this out? I have looked in all my reference books, but no mention of this species, which I assume is some kind of cultivated hybrid / garden escapee? Am I right in that at least?! I do think it's a rather beautiful flower, whatever it is.
One way is to use the iSpot search for Symphytum and see what matches yours.
Thanks for this advice - I'll certainly make use of it next time I have a query about a plant.
