It is comfrey....The comfrey...Symphitum officinale.
There are many varieties. Some with huge leaves that grow quite tall, some with white flowers, blue flowers, pink flowers, pink and blue flowers on same plant even purple ones. Comfrey comes in many guises.
Will check my customers patch on Wednesday Ragdoll and see whether any on there or if yours just have a special flavour lol.
