Bocking 14 Comfrey
Hardiness: zone 4-9
Comfrey is an absolute powerhouse in the landscape and garden. Produces abundant nutritious biomass and blooms steadily throughout the season. Can be chopped and dropped 3-4 times during a growing season, spreads slowly along the ground, and the Bocking series do not make viable seed, so they will spread and creep in place only. Propagates readily from any small piece of root, so be aware wherever you plant them they will remain. Crowns will establish and grow a monster plant in year 1, and rootlets can also produce quite a large plant in a year given ideal conditions. Comfrey also makes a great rhizome barrier; grasses and perennial weeds will rarely be able to find a foothold in an established line of comfrey.
