Symphytum is a genus of flowering plants in the borage family, Boraginaceae, known by the common name comfrey from the Latin confervere to 'heal' or literally to 'boil together', referring to uses in ancient traditional medicine). The Russian comfrey 'Bocking 14' cultivar was developed during the 1950s by Lawrence D. Hills who first introduced Russian comfrey into Britain in the nineteenth century) following trials at Bocking, Essex. Wikipedia
Bocking 14 is sterile, and therefore will not set seed (one of its advantages over other cultivars as it will not spread out of control); thus, it is propagated from root cuttings. You can produce "offsets" from mature, strongly growing plants by driving a spade horizontally through the leaf clumps about 7 cm (2.8 in) below the soil surface. Wikipedia
