Comfrey is noted by both organic gardeners and herbalists for its great usefulness and versatility. Of particular interest is the 'Bocking 14' cultivar of Russian Comfrey. This strain was developed during the 1950s by Lawrence D. Hills, who founded the organic gardening organization now known as Garden Organic. As the world authority on comfrey, he wrote for farmers and gardeners in all countries, showing how this useful plant could be cultivated in both tropical and temperate zones to produce a crop equally rewarding for gardener, smallholder and mechanized farmer.
First published in 1976, this book was the most comprehensive survey of the properties and cultivation of comfrey ever, and "Comfrey" remains undoubtedly the essential book on the subject, as well as a lasting testament to Lawrence D. Hills' indefatigable efforts to achieve a better understanding of it.
