Comfrey is traditionally known as knitbone or boneset with many uses both in the garden and in the homestead. The leaves make for great compost tea and mulching material as they are high in minerals and nitrogen. In permaculture, due to it’s deep tap root comfrey is known as a mineral accumulator and often planted under fruit trees as natural fertilizer.
Also the leaves can be used externally as a poultice to help repair a broken bone by promoting cell division. Propagates easily from root cutting or crowns. Some cultivars are bred not to produce seed to control spreading of the plant. Although we are not of the cultivar, our plants have not produced seeds in the 3 years that we’ve had them in the garden. The leaves have a strong but pleasant odor of cucumber when rubbed.
