Symphytum officinale COMFREY
Live plant of Symphytum officinale.

Comfrey (Symphytum officinale L.) is a perennial herb of the family Boraginaceae with a black, turnip-like root and large, hairy broad leaves that bears small bell-shaped white, cream, purple or pink flowers.
It is native to Europe, growing in damp, grassy places, and is widespread throughout the British Isles on river banks and ditches.
Comfrey has long been recognised by both organic gardeners and herbalists for its great usefulness and versatility; of particular interest is the "Bocking 14" cultivar of Russian Comfrey (Symphytum x uplandicum).
