Symphytum x uplandicum Russian Comfrey I
Symphytum x uplandicum which is the hybrid between Symphytum officinale (Common Comfrey) and Symphytum asperum (Rough Comfrey) was introduced as fodder and for fertiliser but has now spread to many parts of the British Isles such that it is commoner than Common Comfrey. It is fertile and will back cross with Symphytum officinale to give intermediate species. This can make identifying Comfreys quite tricky.
Symphytum x uplandicum is very common in England and Wales and common Ireland. In Scotland its is quite common in the Border country and the industrial lowlands but records become fewer as you move into the highlands and the far north. It is found on the outer islands though north and occurs on the Hebrides, Orkney and Shetland.
