This is a tall perennial herb reaching about 1.4m high with large, lance-shaped hairy leaves, hairy stems and magenta-pink flowers. Russian Comfrey originated from the natural hybridization of the Common Comfrey (Symphytum officinale), which is native to England, and with the Rough Comfrey (Symphytum asperum), which is native to Russia.
It flowers June to August, and is seen growing on roadside verges, banks, woodland margins and waste ground. Introduced as a forage plant in 1870. Frequent throughout the British Isles, except northern Scotland and Ireland where it is rare.
